It's not a wakelock.

It's a general category including many normal operations.

I assume that you are using a custom Rom, right?

I've gotten 4.5 - 5 hours SOT only on data no Wifi. I think it depends quite a bit on your network. If you have a great signal throughout the day then it should be good.

Obviously also depends on what you are doing with your phone. For me it's mostly just Web browsing, tapatalk, messages, emails etc. No games or pictures or any intensive activities.

I use mirage kernel with purity 4.4.4. Greenify some apps. Undervolted as well.
[Nexus 4 General] RASTAVIPER:
I am still waiting for screenshots from the person that claims that he managed to get 5 hours on 3G.

Unleashed by my M1 note
[Nexus 4 General] autoradio78:
For example, in absence of wifi access point at home, with full use of phone in 3G (game,social, media, web browsing) we will get 2, max 2,5 hours. These are the facts, all the rest are words..;)
[Nexus 4 General] 350Rocket:
I usually get 3, but definitely not 5.
[Nexus 4 General] xenyz:
I have got around 5h on 3G, but it was a year or so ago with a younger battery, on KitKat and original Hells Doctor kernel. Search for my username in this thread to see all my experiences over time.
[Nexus 4 General] RASTAVIPER:
You don't count!

You are an alien regarding battery tweaking!! :) :)
[Nexus 4 General] xenyz:
I'm fairly certain the one thing missing from most posts here, and the major factor in SOT is screen brightness. It saves so much battery by dimming the screen, more so than any ROM or kernel tweak.

I have my device set to adaptive brightness with the slider over the WLAN icon, and I'm usually using it indoors, so my results would be better than someone using it outdoors with the brightness cranked up high in order to see the screen.
[Nexus 4 General] 350Rocket:
So I decided to give this a try (even though in all the years reading here, I never saw anyone claim you had to run the battery dead after a new ROM or kernel for it to calibrate) and no it still didn't work. I did some tweaks to get rid of wake locks and only had 3 minutes of awake time over night after I ran the phone right dead and recharged to 100% last night.

So basically the phone drops from 100-90% within a very short time and then drops slower and slower the lower it gets. It only started since I replaced the original battery with a new OEM one. I basically get the similar screen on time with the new battery just the gauge doesn't read correct from full to 90 ish.

---------- Post added at 03:27 PM ---------- Previous post was at 03:24 PM ----------

BTW, it was 5.5 hours screen on time by the time it finally died last night. Which I won't complain about. But I was on it basically non stop all afternoon.
[Nexus 4 General] AlexandreTelles:
~3/4h on 3G and ~8/9h (or a bit more) on wifi is normal? I don't know if is something I made, I changed my use or something else, but as far as I can remember my battery was lasting way more a few months ago (~6h> on 3g and 12h> on wifi). I use CM 11, Hells Core, AcDisplay (?) and about 3 or 4 non demanding apps in background most of the time. And I don't usually check SOT.
[Nexus 4 General] Gemichi:
I think the battery on my nexus 4 has degraded a lot...I can barely keep it up for a day before running home for the charger...average 2 hours on screen time...wondering should I get a new phone new since it has served me almost three and a half years now...waiting for Xperia z4c?
[Nexus 4 General] dcop7:
Three years? Nexus 4 was made available in November 2012, that is almost 2 and a half years, not 3 :)

5h 6min SOT.

Stock 5.1 with root. Latest hellscore with minimum frequency at 94 MHz, on demand governor, event boost disabled. WiFi the entire time with brightness at 1%, Google Now disabled, Location Services disabled, high accuracy location enabled. I'm using Greenify, App Ops, and DisableService.

Phone was used for reddit, facebook, another social networking app that I've erased from the screenshot, chrome and tapatalk.

In terms of wakelocks, it's 3 - 6% of the time.
[Nexus 4 General] :
is there any way to diagnose a battery problem? I'm on cm11 which should stable, my battery was at 50 % and then a of a sudden went dead. I plugged in to charge and it read battery at 1%
[Nexus 4 General] codebam:
I'd check if your bootloader actually says 0% (in the battery icon). I had issues with some ROMs not reading battery percentage properly on clean flashes a while ago. Came up as 1% when it was really at something like 90%. If it's not a software problem it's probably a hardware problem, meaning you have a faulty battery.
[Nexus 4 General] googleygoggles:
Or... His battery might just need a recalibration.

1. Try keeping the phone on for as long as possible.

2. When it shuts down, turn it on again.

3. You need to do this until your phone doesn't have enough power to turn on.

4.Wait about 30 minutes and try to turn on the phone. If it keeps turning on completely, then keep draining the battery.

5. Once completely EMPTY, charge the battery in one go until it's at 100%.
[Nexus 4 General] codebam:
no no no, you are never supposed to drain li-ion batteries to zero, it doesn't calibrate them, it just hurts the battery. do shallow discharges from 80 to 40 a few times.
[Nexus 4 General] 350Rocket:
I tried running mine dead as someone on here insisted that calibration needed to be done and it accomplished nothing other than as you said probably taking some life off of my battery.
[Nexus 4 General] xenyz:
And I was having an issue with the device switching off between 5-10% without warning, recalibrated my battery, and now it's just fine.

I think people may not be running their batteries dead as possible. When I was doing the sequence, I found that even when the phone shut down, I could wait 1 min and power up again. You have to drain the thing.
[Nexus 4 General] codebam:
but only if the software isn't picking up the percentage properly. don't just randomly calibrate for no reason, that'll hurt your battery. for example, one time after a clean flash it showed I had 5% when I had 90% before the clean flash. after draining down that 5% and rebooting it showed the correct percentage.
[Nexus 4 General] SeanInToronto:
In my opinion, you never need to start the phone again once it powers down due to low battery for a successful calibration. If the battery does in fact require calibration, it will be obvious because it will stay at 1% for exceptionally long. Once it shuts down, charge to 100% in one go and the battery should be calibrated.
[Nexus 4 General] xenyz:
The kernel gets the battery information from the battery's fuel gauge. We're talking about recalibrating that device to re-set the low voltage marker, and then charging to completely full to re-set the high voltage marker. You don't have to do it often, and you don't do it for no reason. Leaving your battery with a low voltage for an hour won't hurt it.
[Nexus 4 General] codebam:
I think I read somewhere that you're supposed to drain your battery to about 10% once every month if you want to retain your full battery capacity. I found that to be fairly accurate. only time I've had battery calibration problems was when I didn't do that. I wouldn't drain all the way to 0 though (absolute 0, not what your phone says is 0). I think they can even explode if you try to charge them after that, or just not charge at all. so yes, but I wouldn't say draining your battery that low all the time would be a very good idea.
[Nexus 4 General] 350Rocket:
To make sure my battery lasts in the long term I rarely run it low and almost never run it dead so it took that one attempt to calibrate it to find out it actually would go down to like 2% before dying.

Mine just drops from 100% to 90 fast and the rest drops normally.

Oh and my iPhone 5 dies at like 12% and drops fast below 40% and killing it didn't help so I ordered a new battery.

How people can get so hyped over 5 hrs of SOT if they were scored through 10 hours of usage is beyond me.

You see these graphs that range from 9 AM to 6 PM and they call it good battery life.
[Nexus 4 General] JacobSmits:
I don't know what are you using but I can barely get through one day without my nexus 4 dying. :(
[Nexus 4 General] rondias18:
Its a valid point, but then how long has your N4 been on for the maximum SOT you got? Cause with the N4 10-15hrs usage will get u 4hrs minimum SOT, more than 15hrs usage would give you maximum of 3hrs and so on.
[Nexus 4 General] 350Rocket:
That sounds right for mine. The one time I used it continually with almost no screen off, running multiple apps doing different things and trying to kill it to see what percent the phone would shut off at (2%) I got 5h15 minutes screen on time.

Help! Battery Question, not fully charging upto 100

Battery charging only upto 92%

I've got a new battery just a week ago, as soon as I unplug it on 100 the % drops

If I reboot to recovery after 100% & connected to charger recovery shows 92%

If I let it 100% in recovery and reboot to system again battery shows 92%

Tried calibrating in different ways too, no luck please help.

Is it normal behavior of a new battery or I have got a defective one?

Nexus 4, Euphoria OS 1.1(latest build)

Hellscore kernel (b-78) Same results on stock euphoria kernel too

I found this thread the most convenient for my question, excuse me if I posted in the wrong place
[Nexus 4 General] 350Rocket:
My new battery has been basically the same since I got it a couple months ago. Charges from 92% to 100 almost very fast and drops back down fast. Works fine other than that, although the original 2 year old battery worked just as good. It looks to be a genuine OEM battery only a few months old according to the date on the sticker.
[Nexus 4 General] slybunda:
fake battery
[Nexus 4 General] 350Rocket:
Any idea how to confirm a fake battery? It sure looks real put next to the original one. The only major difference besides the end of the serial number is the manufacturing date.
[Nexus 4 General] mara-:
Why don't you people just go to the official LG service and replace the battery? I paid 20€ battery + replacement.
[Nexus 4 General] 350Rocket:
I don't think there is official service here. And I'm not sending my phone away. I ordered the battery which came in a few days and it took about ten minutes for me to replace. I just want to know if there is some way I can tell it's a fake battery. It will take less than ten minutes to remove it again to check.
[Nexus 4 General] prithvic:
I don't think there is a real way to find out by just looking at the batteries as when I replaced mine, I compared each and every detail written on it, it was carbon copy except for manufacturing date and SR no. Th only way to find out is by performance. The battery I got was without warranty from a local shop at around $6 (350 INR) How much did your battery cost?

(I could have got an OEM or Original battery for around $9 - $10 with 6month warranty, i regret not buying them :( )
[Nexus 4 General] 350Rocket:
Mine was like $16 Canadian on eBay from a reputable seller. I bought at the same time as an iphone 4s battery that looked real but it was almost 3 years old. It was for my girlfriend's iphone which we never bothered fixing.

How well is yours lasting besides the 8% initial drop? That in itself doesn't condemn the battery IMO.

How to Tell if it is A Fake Battery

I have had a fake battery I bought from ebay - I tried it in my phone for a month or so and it worked ok for a few weeks then started acting odd !

The battery life is unimpressive - like a 2 year old genuine one and would suddenly discharge completley from 20% to shutdown the phone - then you'd get the red flashing led situation.

It was then I made the comparisons and noticed the differences.

1 - It is lighter in weight

2 - The dimensions are smaller in depth and width

3 - The most important one - on the back of the battery it is not Silver with serial numbers on as it should be ;)

Otherwise it is Identical.

I contacted the seller 3 months later - who was obviously Asian as he couldn't spell for sh*t and after some cross examination he actually admited it was "non genuine"

So on the phone to ebay for 1.5 hours - they could't give a sh*t - passed me over to paypal.

Nice girl at paypal - said if he had a history of counterfeit goods she could give me an instant refund - and what do you know bingo he has - so instant refund.

What gets me about this though is ebay & paypal are quite happy to let him carry on do this -so they get their commision - CRIMINALS ALL 3 of THEM !!!!!

What a f*cked up world we live in.

I still have the fake battery here ;)
[Nexus 4 General] 350Rocket:
Mine was silver on the back like the original, serial numbers and all. So it looks like mine is probably genuine. Also it will run down to 2% before dying.
[Nexus 4 General] k500zm:
ok - just received a genuine LG replacement battery from ItsTek on Amazon UK. £19 but it's genuine and manufactured 12/14 - Gonna pop it in tonight and give it an overnight power off long charge.

The amazon page says this though - " phone reset might be required when changing battery follow these reset instructions afterwards system/Build.prop update ro.lge.capp_valid_batteryid=false "

Any ideas what this entry to the build.prop is all about ?

how many hours you do with lollipop? wifi /3g?
[Nexus 4 General] Flipz77:
About 2h 30m SOT over 16 hours of medium/heavy usage, fairly split between wifi and data. The only real (which for me means requiring regular operation on the user's part) measures I take for lowering unwanted consumption are manually toggling sync while on data (well, most of the time, I'm no robot) and locking the radio to 2G when I'm busy and I know I won't need quick, on-the-fly internet access.

Custom ROM and kernel (I have to admit I tweak for performance)

So far my battery life is rubbish on my N4, down to 43% in 3 hours of moderate use, î appreciate the advice about turn this and that off to extend battery life but that's the reason I got the phone because it can do this and that I don't want to turn them off, it seems to me that there is an issue with the kernel which should be remedied with updates, fingers crossed. I had a HTC one s which would do the same stuff and last well over a day but I prefer the untainted Android experience. good to see that some are getting reasonable life out of theirs though.

[Nexus 4 General] shadehh:
can't believe android system used up 24% of your total battery. In theory if it were not that high you'd easily still have 50% battery with 2 hours 38 minutes screen on time since your 33% android system translates to 24% of your total battery.
[Nexus 4 General] jaZzyjeff818:
Wow I barely pulled my phone off the charger and I'm already at 94%. This is starting to depress me.
[Nexus 4 General] OverTheBelow:
I've noticed that brand new rechargeable batteries take a little while to get to their full potential. Give it a few days of use and you'll notice that your phone battery is lasting longer and longer, and or draining at a more consistent pace (e.g. not going down to 20% in half an hour, then taking 2 hours to go down to 10% with the same usage). My extended battery for my previous phone got stronger in a few days, as did my digital camera battery.

In short, it seems evident that there is a burn-in period for these batteries.
