Hello HTC users,

I know this is an old phone that may only be used by only a few people now, but I am still owning one and I recently tried to give it a cosmetic refresh.

It went from this (I know, "how the hell did this happen??!!"):

View attachment 5780365 View attachment 5780367

To this (back cover is not glued yet):

View attachment 5780369 View attachment 5780371

What I have done:

Replace the screen (I initialy wanted to only replace the outer glass as the screen was still working... but I lack the equipement & skills to do this)

Replace the back cover

Replace the aluminum chassis

Replace the battery

Replace the fingerprint scanner

The "rebuild" went quite well as the only thing I was not able to disassemble from the old chassis are the pressure sensors: everything else I was able to disassemble and reassemble smoothly in the new chassis. The phone boots, the screen is ok even though it is an OEM one, speaker and microphone are working, physical and sensitive buttons too.

BUT (you saw me coming 😅)

While I am pretty sure that I did not riped or damaged anything during the rebuild, the fingerprint scanner is not working anymore and the phone is now really really really (really) slow to charge... like 5 to - 6 hours to 100% 😕

I've checked that every flat cable is correctly connected and they are. Then I tried:

To connect the old fingerprint scanner instead of the new one: it does not work anymore.

To connect the old battery instead of the new one: android still tells me that I am stuck with slow charge.

To clean the charging port (which was insanely full of stuff by the way 😲): still no fast charge.

To boot into recovery mode and clean the system cache: still the same.

I have the feeling that this is an Android related issue and not an hardware one but it is only a guess... and I don't know where to search now.

I hope someone will read this and have some advice 🤞
[HTC U11  Guides, News, & Discussion] metropical:
I just re-batt'd and new back on my HTC U11. Sorry I didn't replace the charge port PCB as well.

My $ is on that PCB, if you care to spend another $15 and dive in again.

Pretty sure the fingerprint thingy is tied to the same PCB.

Also, be sure you have FC 3.1 cable. I got my parts from Sunsky in China. I think about 2 weeks door to door.

But it will now be my b.u. as I bought a Pixel 5 to be the daily driver.
[HTC U11  Guides, News, & Discussion] teamnowhere:
Thanks for your feedback! I don't mind diving in again, that's why I still haven't glued the back cover ;)

How could I be sure that's the root cause?
[HTC U11  Guides, News, & Discussion] metropical:
No way I'm aware of, unfortunately.
[HTC U11  Guides, News, & Discussion] teamnowhere:
So! I have finally been able to replace the daughter card and you were right, it solved almost all my issues: fast charge is back, microphone works.

Thanks for the tip! (y)

The only thing that still does not work is the new fingerprint scanner. I tried to clear the system cache, clear the fingerprint scanner app cache, reboot the phone etc, nothing worked. In fact I cannot access the "fingerprint scanner" settings, it launches nothing when I press it.

I tried to connect the old fingerprint back and with this one I can access the menu... but it does nothing when I try to declare my fingerprints :cry:

I'm starting to wonder if this is not software related.
[HTC U11  Guides, News, & Discussion] metropical:
1st thought is to boot into safe mode and see if that clears the problem.

2nd thought is to back-up and factory reset and reinstall AOS 9.
[HTC U11  Guides, News, & Discussion] teamnowhere:
I've tried to boot into safe mode with no luck... I'll try to factory reset this week-end!
[HTC U11  Guides, News, & Discussion] teamnowhere:
So, did a factory reset this week-end and unfortunately the fingerprint scanner/home button is still not working 😞

The only difference is that now the fingerprint scanner menu in the Android settings has now disappeared... which makes me think that the issue is software related. But the phone is old and I can't find similar problems: it's a shame!
[Google Pixel 6a] lallolu:
I got my first pixel about 1 month ago and I have to say that it has the best battery life of any smartphone I have used. It is even better than the LG V30s and V50 which i think had great battery life. It is definitely better than my S21 5G (exynos). It is very efficient during use and really awesome in standby. However, I am not rooted and I have disabled 5G and AOD. I attached some screenshots. Note that I was on wifi about 85% of the time and my usage won't be the same as yours. But this is just to give an indication of what could be achieved with the pixel 6a.

[Google Pixel 6a] Tomatcree:
I agree, tis a very good battery and managment. Pixel 7 has an even better one....
[Google Pixel 6a] lallolu:
I gave up as I will be going out soon and I need the phone to be charged. it has been at 6% for about 2 hours and i don't even have it in battery saver mode and I still have auto brightness by default. I am loving this battery life.

[Google Pixel 6a] Zaxx32:
If you root, with various tweaks you can squeeze approx. 15-20+% more outta it. GMS is a freakin' hog...you can tame it plus force numerous other system apps to doze muuch sooner. That's just a few. 😉
[Google Pixel 6a] charly30:
which tweaks? how to doze GMS??
[Google Pixel 6a] Lada333:
Xda Doze Gms

For those who think it's easier to annoy you than to Google 'Xda doze gms' themselves.

[Google Pixel 6a] sam00561:
Yes must admit bought mine 3 days ago and battery is the best in any phone ive had including the Lenovo p2 with 5000mah battery if anyones old enough to remember that
[Google Pixel 6a] ctfrommn:
3a XL was better
[Google Pixel 6a] Alldayismokebomb:
One plus 10 pro. Takes 20 mins to go from 0 to full charge and last forever !!!
[Google Pixel 6a] nahsha:
Battery consumption really improved on January build.. I'm at 18% remaining with 7h 40 min SOT.
[Google Pixel 6a] dexlemaffo:
Stable or QPR Beta 2 -2023?
[Google Pixel 6a] nahsha:
Stable
[Google Pixel 6a] Stirth:
My girl with iphone 13 pro with same battery but 6.7 120gz screen with max brightness all time have stable(!!!) 8-9 screen on time. With VPN and all is on. I look for iphone now. Pixel is good as android but iphones is the most optimized device.
[Google Pixel 6a] sam00561:
we dont like discussing Iphone here in fact i think it is out of bounds per rules also.
[Google Pixel 6a] Skochko92:
So, if I understand battery on 6a is now better than average?

How about heat management, does the phone tend to get warm or hot on basic tasks or prolonged use?
[Google Pixel 6a] sam00561:
I have never noticed any heating issue at all although i never game on phones.
[Google Pixel 6a] marion695:
any tips to improve battery?
[Google Pixel 6a] Lada333:
What do you need improving on?
[Google Pixel 6a] marion695:
View attachment 5837847

is this ok with my battery?
[Google Pixel 6a] Lada333:
This barely tells me anything. If you're happy with your battery life, then I guess you don't need improving.
[Google Pixel 6a] phaleg:
I agree, I can have 2-3 days with the same charge, but the problem is to charge it in my case...

Mobile arrived without charger, I used the one from OnePlus 3T and it often stops around 20-30%,

I tried fast charger from my father's Motorola and does the same issue.

It charges easily only with basic and older chargers,
[Google Pixel 6a] marion695:
try samsung charger

https://www.amazon.pl/Szybka-ladowarka-port-typu-kabla/dp/B08P95B5FR/ref=sr_1_12?keywords=samsung+charger+25w&qid=1676540783&sr=8-12
[Google Pixel 6a] marion695:
im not happy,battery is for 1,5 day only
[Google Pixel 6a] Lada333:
Yup, that's about how much the 6a can do on average. You should've read some reviews before purchasing the device.
[Google Pixel 6a] mike.s:
You need a modern charger which supports standard USB PD (Power Delivery), and preferably USB PPS (Programmable Power Supply) capability. Older "fast chargers" used proprietary methods (such as Qualcomm Quickcharge). Pixels only support the USB standards, and older chargers often won't charge quickly, and won't charge as quickly as a Pixel is able to. Look for a USB PD/PPS charger of 20 W or more.
[Google Pixel 6a] Lada333:
No need to look for anything over 20 W, as the 6a supports 18 W charging at most.
[Google Pixel 6a] phaleg:
Woah, thanks to both!

I will search first if any of the ones I have have this feature PD/PPS and if not, I will buy one with 20W or less :)

Is that feature a detail that I can try to read among those smaller texts in the charger itself?
[Google Pixel 6a] Lada333:
Not sure. This is the charging brick I got with my phone (not sure if it was bundled with the 6a or the 4a I used to have).
[Google Pixel 6a] mike.s:
But other Pixels and devices do support more. So if buying a new charger, might as well do some "future proofing."
[Google Pixel 6a] mike.s:
... or more. It could be a 100 W charger, and your phone would only use what it wants. Better to buy larger than smaller.
[Google Pixel 6a] phaleg:
Well, I am not expert, but when I used a charger from a new Motorola with fast charging values, it stopped to work around 20-30%
[Google Pixel 6a] mike.s:
That's meaningless without saying exactly which charger you used. Was it a USB PD charger? If it didn't have a USB Type-C port, it definitely wasn't. In any case, USB PD is an industry standard, and any charger which properly supports it will work with a Pixel. Motorola uses a proprietary charging method called TurboPower (which seems to be Qualcomm Quickcharge 3.0, but they're not clear). Only some of their chargers support USB PD.
[Google Pixel 6a] Lada333:
Sure, or even buy like a 250W one, so he can charge his laptop as well.

Or, just buy a 20W for cheap, that satisfies all his charging needs.

If he's got other devices that support PD, chances are, he's already got a charger (which is very likely more than 20W) which he could then use for his phone. Unless he's looking to buy a laptop, a new one, or any recently released piece of technology that supports PD, I would advise against spending a lot of extra money for a charger he's not going to use at full capacity anytime soon.

Like @mike.s said, without knowing what type of charger it was specifically, this unfortunately doesn't mean much.
[Google Pixel 6a] phaleg:
Not sure which model of mobile had my father. Charger came with the same Motorola new phone and has USB-C, it is turbo something and on the side, you can read the big numbers of 33, probably referred to 33W?

About PD, I checked each charger I have at home and none had PD/PPS written among the super tiny text that is written on the charger, but I found a humble charger from Honor that without any frill charge it for normal speed.
[Google Pixel 6a] natheux:
I charge my pixel 6a with a 20w baseus charger I bought from ali in 2021 I think and it's fine (+ it has usb A and usb C which is convenient).

I recently bought a usb PD charger (100w) so I can charge my laptop, my phone and others things at the same time and it's fine.
[Google Pixel 6a] djp090:
Hi.

I'm not happy with my battery.

During the night, in airplane mode, in only 8 hours, it goes down 9%

Is it normal? Only 2 apps: Google and Inactive mobile (translation from Spanish).

Will a hard-reset improve it?
[Google Pixel 6a] ctfrommn:
No, something is causing issues. ~0.5%/hr is normal with everything on. I assume youre not using AOD? That will definitely use 1+%/hr
[Google Pixel 6a] a4arjun:
Seriously? Mine drains like hell. Atleast 2% per hour when idle. My device is new, 6 days old and shipped with Android 13. Will that be a device specific issue? Shall I return it or claim a warranty?
[Google Pixel 6a] sam00561:
Install Hentai is all issues solved
[Google Pixel 6a] phaleg:
I had the same, I did hard reset and one got battery to zero by purpose as instructed (I don't remember the order of these 2) and it all got back to awesome ... Anyway I sold this phone yesterday and got back to Pocof1
[Google Pixel 6a] a4arjun:
Thanks for your response. I'll try a hard reset and battery draining to 0% and let know if it fixes the issue.
[Google Pixel 6a] phaleg:
Right after, remember to charge completely without interruption:)
[Google Pixel 6a] a4arjun:
UPDATE: Did the same, but problem still exists. May be a hardware issue (?). But, battery drain is normal when using the phone 😂
[Google Pixel 6a] phaleg:
I did it twice and the second time, it was okay, (factory reset + battery to 0% + complete recharge)
[Google Pixel 6a] gtown1707:
I am really impressed, reached over 10h sot with more than 4h tiktok, 6h whatsapp and 2h youtube of useage. Screenbrightness set to 50% most of the time btw.

On datasheet the battery are smaller compared to my old phone, but batterylife are much better.
[Google Pixel 6a] a4arjun:
I'll try it again. Able to get a SOT of 5-6 hours in the last 24 hours. Is that normal? These people are claiming 8-10 hours easily. Drain while idle remains the same (2% per hour)
[Google Pixel 6a] phaleg:
I used to get easily 3 days with it, but probably I'm not a heavy user
[Google Pixel 6a] Proud2banoob:
As the phone ages and gets a record of your use habits, battery life will improve.
[Google Pixel 6a] TechX1991:
I stopped using my 6a because the battery life was so bad lol Went and downgraded to a OnePlus 8t with LineageOS MicroG
[Google Pixel 6a] a4arjun:
You're making me upset 😭. I tried it again and it got even worse. Yesterday it dropped from 42% to 2%
[Google Pixel 6a] phaleg:
Get in touch first with Google assistance, they will give you some test to do and advice accordingly

It's unpleasant but it can probably be fixed
[Google Pixel 6a] ctfrommn:
Lol, depends on what youre coming from and used to. The modem in these is garbage so if youre on cell data a lot and especially if you have poor (to even avg) signal battery life and temps will be terrible. Add to this any kind of streaming video, or taking videos and it gets even worse.

I would definitely recommend starting by turning off adaptive connectivity, WiFi and BT scanning, and change to LTE if you dont need or cant use 5G. These will help but nothing will solve the issue entirely.

That said, in my use case this is as good as any device Ive owned. 2 days off charger and and anywhere from 8-12 SOT is normal depending on what Im doing.
[Google Pixel 6a] a4arjun:
I tried removing the SIM card last night. Results were surprising. I just lost around 6% in 12 hours! Checked some answers from Google support itself. Pixels has some bugs with the imsService wake locks.

"imsService" requesting Location data every 60 seconds, needlessly draining the battery. - Google Pixel Community

I checked my phone after inserting SIM card back, and the moment I reinstalled it, ims service started accessing location. Let me know if there are any fixes for this
[Google Pixel 6a] senq87:
turn off the nearby places feature in the phone app. then check battery usage
[Google Pixel 6a] amm0nium:
This phone has the worst battery ever seen by me.

Around 8-10 hours of mediocrely intense use.

It drains 6-10% per hour just by being idle, WTH.

Ok, it doesn't take that much to charge (around 3 hours when ON but with screen OFF, or around 2 hours when OFF), but still it's very unpleasant
[Google Pixel 6a] Lada333:
Are you sure there's not an app that's keeping a wakelock?

Do you have bad cell reception when the phone drains this drastically? If so, there's not a lot you can do. Unfortunately the modem is horrible in these devices. You could turn off 'keep mobile data always active' in the developer settings. It might delay some notifications, especially if you're not on wifi, but it will likely decrease the idle battery drain.
[Google Pixel 6a] amm0nium:
Nope, no apps, see screenshot below of just the "system usage" section. That's 120m and 32% battery, so 1% drained each 3min 45s, it's ridiculous.

I have variable cell reception, as i move within a 30km radius every day back and forth. When stationary (work/home), reception is good, but i am also connected to wifi, not using mobile data, both at work and home.

It's so unpleasant having to disable feature after feature in order to have a usable device.

Well, instead of a phone with half the features disabled, it would be better to buy a different one....
[Google Pixel 6a] bernardblacksbookshop:
ill say mine is acceptable not great . coming from a poco x3 nfc having to charge once a day does seem like a step backwards .maybe it'll sort itself out with the next update . still seeing loads complain about battery life across various pixel phones . they seem to fix the drain for some and give it to others lol.
[Google Pixel 6a] amm0nium:
I had problems getting worse and worse since when i bought the phone in october.. i know for sure that i have way more apps now compared to 8 months ago, but my battery never ever lasted what people wrote in this thread.

Updates didn't make a difference
[Google Pixel 6a] Lada333:
Have you done a factory reset since then? I remember I started having worse and worse battery drain as well, but most importantly a few apps needed to be restarted 2-5 times before they registered that I had active mobile data. I was told a factory reset would solve the issue. I went two steps further and flashed (since then, several) custom ROMs - neither of my previous issues ever showed up again.
[Google Pixel 6a] graewulf1:
i'd love to know how so many people can get days out of this phone battery. i have had mine for about a week now, and find the battery life is about half of my Moto G Power 2021 (2 years old BTW). If I am lucky, I have 40% left by bedtime, whereas my Moto would regularly have 50-60% left after normal daily usage (not sitting in my pocket, actually using it). Screen kills this battery fast, with my usual usage i might get about 4 hours screen time compared to 9-10 hours on my Moto with similar usage. I didn't tweak anything on the Moto, just normal stock settings on android 11 for the most part.
[Google Pixel 6a] Lada333:
Tbf, people that boast several days on a single charge usually don't really use their phones at all + have everything underclocked, very aggressive doze, etc.

If you usually get 40% left by the end of the day, you might want to charge your device to only 80% instead of 100%. It'll leave you 20% by the end of the day, but it's definitely going to help the longevity of your battery.
[Google Pixel 6a] graewulf1:
The 80% rule doesn't make much sense to me. In 2 years most batteries lose less than 10% capacity when charging to 100% every day, so it doesn't make much sense to not fully charge daily. Plus, I've had 2 days where I was below 30% at bedtime, 40% is more the "average day's usage". I'm kind of disappointed since this battery is 88% the size of my moto, and yet the moto got over 2x the screen on time that this phone gets. I was expecting to be able to get a least 8 or 9 hours screen time out of this battery. Heck, the moto, after 2 years of charging to 100% daily, still got 10 hours screen on time out of a 5000mAh battery, no aggressive battery saving measures in place either, standard settings. It has to be a power management issue on this phone.
[Google Pixel 6a] TechX1991:
Not quite the best, my oneplus 8t edges it out a good fair bit, and I have one of the Duracell android phones with the like 10k mah battery
[Google Pixel 6a] Lada333:
Might want to read up a bit on how modern phone batteries work. But, sure, if you plan on buying a new device every two years, you can get on fine without caring about it.

This is usually true, plus some pieces of the hardware aren't very good either. For example, if your device spends most of its time with bad cell reception, you're going to notice a hilarious amount of battery drain - the modem is just horrible.

From what I've gathered, Google was (or still is) very much working out how the Tensor chip works, therefore the software optimization tricks that worked well on Snapdragon might not work so well with their own SOC.

If you're into flashing custom ROMs, I'd definitely look into what's available nowadays, the battery life is usually much better on them. One of the main reasons I switched to using a custom ROM after like 6 weeks of owning the phone was questionable battery life. On crDroid I got 0.2% - 0.4%/hour battery drain overnight, which is outstanding.
[Google Pixel 6a] graewulf1:
The main reason I got the pixel is for the custom ROMs. I'll play with them eventually after I look at what is available. I am partial to LineageOS.
[Google Pixel 6a] amm0nium:
no didn't do any reset..

but my phone has so many problems.. mic not working when on speaker, gps+accellerometer are off, ghost touches with screen off -i called my emergency contact 5 times in a month-, device gets scorching hot at any moment -i don't live in a tropical climate dammit-, and so much more....

it's unbearable, so i spoke yesterday with the reseller (amazon) and got a refund, i don't think i'll buy the same model...
[Google Pixel 6a] Lada333:
Yup, those are all very likely due to horrible software from Google and not hardware issues, and can be solved by factory resetting/flashing a custom ROM.
[Google Pixel 6a] amm0nium:
WTH.. lol i don't know what to say.... think i'll buy another brand then.. i think i'll go for cheap and stupid phones, since even the relatively pricy ones can be this bad, and i cannot afford (and don't want) an entire-month-of-work-worth of phone (1k+€)
[Google Pixel 6a] udance4ever:
skimmed this thread really quick & just thought I'd chime in...

I use AccuBattery & after 12 months, I'm surprised the battery is 99% of spec (4379 of 4410 mAh) after 279 cycles.

I used to have drain issues early on & as others have posted, the device learned my behaviors & now it's great. I also had overheat issues & these seem to have gone away as well. I definitely notice it deep sleeps really well.

I did make sure to remove any background processes I didn't need but all in all, I have 8 (of 98 installed) apps that use location all the time (eg. Fit, Maps and three 3rd party apps). The Pixel seems to manage them all pretty well.

I'm pretty satisfied with my 6a after trading in my 3a in Aug 2022. I will say that I doubt I will keep using my 6a for the 5 years of security updates it's slated for (July 2027), let alone the 3 year typical lifetime. Time will tell.

Not sure if any of this helps - just thought I'd add a few data points!
[Google Pixel 6a] sam00561:
i think the good battery health after all this time is probably due to the manufacturers limiting the charging to 30w which will help battery longevity unlike the likes of Xiaomi etc offering 50 and 60 watt charging speeds
[Google Pixel 6a] Lada333:
That's not necessarily true. First of all, the 6a can only fast charge with 18W, second of all, it's not the charging speed that degrades batteries quickly, but the amount of heat they generate in the battery while it's being charged. Xiaomi and Oppo can have upwards of 100W of charging speed because most of the heat being generated is at the charging brick and not inside the device/its battery.
[Google Pixel 6a] ionut310:
Exactly due to this. Very fast charging is nice to have but without a software toggle to activate it only when needed its detrimental to the battery in the long run. If i come home and have no plans to go out whats the point in charging my phone in 20 min instead of 1 hour+.
[Google Pixel 6a] sam00561:
Ah I see it's 18w charging don't know why I thought it was 30. Not sure about the charging brick thing tho because when I had the Poco f3 with fast charging the whole phone used to get hot while charging
[Google Pixel 6a] ionut310:
These two are correlated. If you push 20V at 3 amps (60W) the battery will get hotter than at 9V 3 amps (27W). There is no way around it. How hot the charging brick gets is irrelevant.
[Google Pixel 6a] sam00561:
Yea this seems logical
