battery charging

What I have done across all 3 of my EVO's (4G, 3D, 4G LTE) is put on charger overnight, when I get up , unplug, check mail,fb, etc, put back on charger in vehicle on way to work til I get green, unplug for a few, and charge again til I get green. This method, over the last almost 2 years has given me the best battery,especially w/ 3D & LTE...going all day and evening with LTE.:)
[EVO 4G General] itrs:
I could give it a shot. seems like it would work for that one day that this is done after that it's downhills. All the phones i have ever had go to 100 and pluge to 90 and goes down steadily. Even if I charge it and unplug it as soon as it hits 100, actually lasts just a min or two longer before it plunges.
[EVO 4G General] Chirpout:
Just face the facts, with an Evo you NEED an extra battery close.
[EVO 4G General] itrs:
I tried the OP advice, but I didn't see any results. Been 8 hours and phone was at 12% before I just started charging again. I may just buy an extended battery but that would be hard to hide with my no phone workplace.
[EVO 4G General] MBQ_:
Yeah, extended batteries are a lifesaver. Plus they're pretty cheap on Amazon. :)

XDA Mini S battery drain - reg

Hi

I am new to this forum. I have XDA Mini S. The new battery is getting drained within 20 minutes after full charge. Can you suggest how to go about it?

Thanks.
[EVO 4G General] bimmerman7:
Yeah....get a new battery dog!
[EVO 4G General] ocostich:
I just got a Incredible and noticed this battery life thing. Is this just to condition the battery? If so, has anyone tried this with an external charger? SHouldn't it do the same thing?

I also found another procedure that promises the same result at http://xdaforums.com/showthread.php?t=712990 in the first post. Has anyone compared the two?
[EVO 4G General] Poisonman:
I have a HTC Rezound with similar battery problems, I'm gonna try this method and see if it helps solving my battery drain after disconnecting the charger.

Thanks

First time, couple months ago, I tried this thing, but I had an issue: the led was orange for a long time. (HTC Amaze) About 45 minutes. So I did just a couple times (maybe 5 but I couldn't use my phone for a day)

And now I bought USB current meter and decided to test the process again. As long as original HTC charger gives dynamic current, I can monitor charging through the tester.

From real charging to trickle charge (on close to zero) it goes in 30 seconds since the plugin. :) (~15 sec. 0.3A, ~15 sec 0.1A, then 0.06A for rest of the charging)

= 05.09.2014 =

I might write a lot about how I try this with

my phone

Continuing with testing

My device was ~100 on wire, I disconnected it, switched it off and kept charging for ~hour or so. Somewhere in the middle of it current on the display stopped changing from 0.06A but the led was orange.

Since some time it went green but the current level was the same. So, there might be kind of trickle charge program into my HTC that doing it. ) I don't know. In a few stages it comes to 30 seconds for voltage drop, but led will be still orange.

I'll try do the procedure with going to recovery or just turning phone on on each iteration later. I might have not a good battery. ) After 1.5minute turning on it was 90% (and was charged not until green led before). Maybe it just can't held properly energy close to 4.2V. And I should let go and buy an iPhone.

upd.

Well, forget those words. Results may vary with battery, its developer, its electronic – not only cell quality. My assumptions.

So, that result I got on Anker. Now I'm on HTC battery, which can be really loaded to 100% state by phone measurements (don't know exact voltage, it seems, anker's electronics had a little smaller value)

more offtop:

I tried technique on Anker's batteries. Now I returned to stock HTC one (I mean, battery :) not phone). Which is more stable. (also my one had kept original capacity very good – was used for a month since buy, I suppose)

I mean, I can see when it's 100% charged. Which I hadn't seen so far on Anker.

And this level I can get with phone charging, but not on the chinese battery charger. (it's close to max, but it's not, ~95%)

Trying this now! Will report back.

I also have the 100% to 90% issue in a matter of a couple minutes off the charger.

Edit: Can confirm this works. Battery hasn't dropped from 100 yet and its been 5 minutes.

Nice Find Thanks!

[EVO 4G General] mongoose8p:
VERY TRUE everything he says !!! Li-Po batteries in RC/CARS, Planes, ETC. need to be balanced and most lipo chargers for such batteries have a balancer in them! So, what I'm saying is this makes total sense, someone should build an app that would be awesome or somehow integrated into firmware.

I noticed something like this the other night. I had been doing things around my house and needed to charge my Evo before I went out. After charging it in the AC outlet, then to USB, then back to AC, I noticed my battery lasting much longer before dropping the 10% it usually drops within minutes. Sometimes it drops from 100 to 99 within seconds of being off the charger, but last night, it stayed at 100% for at least an hour.

This definitely works.

this actually seems to work lol. Thx for the tip man!
[EVO 4G General] slackjawedhippy:
Over the weekend, I spent several hours tinkering with root, custom roms etc. I was plugging in, and unplugging quite a bit while I already had the phone charged at 100%. Without knowing it, I had actually done these steps. At about 24 hours off the charger, I finally plugged it in at 38%. Awake time was about 7 hours. It dropped quite a bit at the end because I watched a handful of youtube videos. Either way, based on this, I think I can potentially confirm that it works.

However, this morning, it dropped 10% in the first hour. So I'm trying it again to see how it goes. I'll update with my results..
[EVO 4G General] leeh41:
Worked for me! Great post.

My battery used to drop from 100-90 almost instantly after I pulled it from the charger. It now hangs around 98 for quite some time. Still doing this, since I didnt get a full 10 plug/unplugs in the first time.

Proof of not, I feel like I'm just "topping off" the battery... whatever it is, I'm pleased. this method + damage control rom has been working great. Poor battery issues are gone.
[EVO 4G General] slackjawedhippy:
Question - does this procedure require exactly 10 cycles of steps 1-3? Or are we repeating the cycle until some kind of indicator such as the light starting out green (instead of orange) when plugging it back in?
[EVO 4G General] rahb0sse:
Going to give this a shot... battery was at 50% in 5 hours...
[EVO 4G General] icantdrawanime:
I did this last night after flashing the "buglessbeast" rom onto my phone. The combination of the two seems to making a huge difference.

My phone stayed at 100% for ~50 minutes on standby after taking it off the charger.

I watched a few youtube videos on 3g and fiddled with it for around an hour, the battery is currently at 80% 5 hours off the charger

Not sure if this method is the exact reason why my battery improved so much, but thats my experience.

Before I did these things, my battery would drop around 4% per hour on standby...

Wow, you use kinoki footpads too? I feel much more energized since I use them.

The question is, can we really do this manually? Or do we need our kinoki footpads while we balance our cells, and our Qi?
[EVO 4G General] pokerjv:
Not sure if I did this correctly. Am i supposed to repeat steps 1 through 3 or just 1 & 3 like the OP suggested? I have already done it using the 'repeat steps 1 through 3' and it didn't help. If I do it with just 1 & 3, that means I should unplug and plug it back in even if the green led is still lit? what did everyone else do?
[EVO 4G General] cary328is:
WOW! My battery is FINALLY staying at 100% without that 4-6% initial drop after a few minutes! Thanks to OP for posting this. I was wondering why that small drop in % was occurring but this definitely fixed it. :D
[EVO 4G General] m_1000rr6:
This little trick worked out real well! After a combined 2.5 hours of standby, wifi browsing, and texting, my battery had drained down to 90%. Before performing this trick, my battery would drop down to 94% within 20mins. of removing the phone from the charger.

I'm running DamageControl v3.0 ROM + OverclockWidget.

Great post, OP!
[EVO 4G General] rahb0sse:
Only 4 programs running, 23% battery lose in 1 hour.

I did this trick, turned off gtalk and calendar widget and I'm sitting at 3964mV (80%) after 9 hours off charger. This battery I bought off of amazon, the original was charged and in my bag for a backup. I have 4G off, Wifi on, bluetooth and GPS off.

Hi gentlemen,

I have been reading all your post in regards the Evo battery life and felt that I should post my experience and see if this can help someone like it has done for me. I am not by any means disbelieving the findings from the creator of this post.

My experience for the last 2 days has been the following:

On Saturday night at around 11:30pm I just had my evo charged fully to a 100% and while researching this site I found out while on the dialing keypad if you type *#*#4636#*#* it gets you to the Testing menu.

Then I selected "Phone Information" and scroll down to "Set preferred network type" and open that menu and found my setting to be at (CDMA auto (PRL)

I then noticed thta there is an option for "CDMA Only" and decided to change my Evo to that setting and press home after which confirmed that it stayed at that setting.

After that I went ot sleep and woke in the morning at around 6am because I had to pick someone at the airport and looked at the phone and to my surprise it was sitting at approximately 97% after 5 hours on standby.

Then over the rest of the day I surf for quick searches of 5 to 10 mins about 7 times, texted over 40 text messages, had about 6 or 7 calls of about 2 or 3 mins at the time. I then play with the phone for a little while no more than an hour.

And to my surprise I finally charged my phone again on Monday June 14, 2010

My settings:

* Mobile Network Off (Unless I need to search for emails or Whatever)

* Wifi Off

* Animations Off

* Display set to Auto

* Auto lock set to 30 seconds

* Wall paper set to a Black screen setting

I just wanted to share my experience and sorry for the long post.

By the way, right now as I'm typing this to you guys I am running this test again and started at 11am and is right now 8:26pm and my evo still at 75%

Again my own experience without trying the method mentioned here
[EVO 4G General] rahb0sse:
No, I even disabled Gmail calender updates... I don't see calendar running anymore but the battery still is sucking my juice... 11% in 20 minutes of Pandora streaming. We'll see how it fairs today, I'm really debating on rooting before official 2.2. :confused:
[EVO 4G General] sweethip:
Well i can say this worked for me yesterday.. finally it stayed at 100% for about 25min. I was getting a 3% drop after 5min off the charger...

BUt this morning.. i let it charge over night, and unplug this morning and it drops within 3min to 97%..

SHould we do this method a couple times? it was working great yesterday for me..
[EVO 4G General] thecodemonk:
So I tried it this morning after a full charge over night right after I woke up...

After the usual streaming of Rhapsody while I showered, the battery is normally below 90% but today it's still above it even now that I'm at work (after reading my news feeds on the 20 minute bus ride).
[EVO 4G General] pecosROB:
So do we have to do this everytime we charge our phone (i.e. everyday) or just once in a while, or just the first time?

I noticed after doing this over and over my light usually turns green around the 1 minute 15 second mark. Pretty consistent too, around 1:10-1:15.
[EVO 4G General] riverajuan:
This morning I checked the overnight standby and I was sitting at a 100% since charge at 1am and now at ten I already made some calls, text and now sitting at 90%

This same thing happened to me... Yesterday my battery was at 100% for ~50 minutes. Today it seems to stabilize at 96%... it dropped to 96% about 20mins off the charger and hasnt moved since.

Could it be that the internal monitor that tracks battery charge is inaccurate? If thats true, someone could probably write a process that will reset your internal battery charge monitor after the battery hits "100%" and do this ~10 times to simulate the process described in the OP...
[EVO 4G General] JustinChase:
Mine has been "fully" charged for the last 20 minutes, but the light doesn't turn green.

how long should it take once fully charged?

I'm looking at both the indicator on the widget bar and the phone, battery status screen, and both are fully green, just not the LED. It just stays orange.
[EVO 4G General] JustinChase:
okay, my phone just restarted itself. I have no idea why, but it's the third time in 2 days it's done that (I may go exchange it).

But when I came back on, the LED is now green.

very weird.
[EVO 4G General] Dunny9352:
So should I do this only three times, or should I do it tell the light turns green when I plug it in. I swear vie done it thirty times and every time I plug it in it stays orange for a little over a minute (I did count it out) every time.
[EVO 4G General] pokerjv:
I've read somewhere else on another forum that once the charger reaches fully charged..ie 100% charge, that it stops charging. Meaning it doesn't trickle charge. So for example, if you plug it in at 10pm and it takes 2hrs to fully charge, then at midnight to the time you unplug it, it acts as if its not plugged in at all....ie.in standby from midnight onwards. So when you finally unplug it and turn it on, it drops to the correct battery charge amount.

Anyone have any thoughts on this theory? It explains why the OP's process for charging gives us such great results....because we are monitoring the phone charge immediately after taking it off the charger. Sorry for the long post, hopefully it made sense :)
[EVO 4G General] pecosROB:
I'm right there with you man. I've done it A LOT and it helps retain a charge over 90% longer, but not very much after that...
[EVO 4G General] sw99:
Yeah, I've seen the same thing, and the recommendation was to charge your phone in the powered off state - that hardware charging circuit works better than the software one. Have not really investigated it fully, as I needed my phone on overnight for the last couple of weeks.
[EVO 4G General] kthejoker20:
Just wanted to bump this for those still having battery problems.
[EVO 4G General] oubravs2b:
Wanted to thank the OP for this. I actually did both the other battery fixes last night (this one, and set to CDMA auto so not trying to find GSM signal). I charged to 100% and haven't put it on a charger since.

This morning, I go downstairs to find that I had set a test alarm last night and it had been going off for an hour with the screen on. I thought "well crap, that's going to ruin my battery test". I can say that right now, I have 50% battery left. Uptime and Awake time are below:

Uptime: 18 1/2 hrs.

Awake: 2 1/2 hrs.

So 2 1/2 hours of usage throughout the day (texts here an there, a little web searching, reading and responding to emails, jacking with some apps) and still at 50%. Before these two fixes were posted, I already would have switched batteries once. Thanks OP!
[EVO 4G General] Minjin:
That doesn't make any sense at all. There is no difference between charging it on or off except that one consumes more power at the same time than the other. The idea that it is using two different charging circuits is silly.

The only thing that's happening here is that you're circumventing the lithium batteries automatic shut off. You charge it till the battery hits a circuit voltage. The lithium cell shuts itself off from the charger. The battery slowly self decays and the voltage goes down. If it goes down below the cut off voltage, you can do some more charging but that little bit of top off that you're doing doesn't add much and it probably isn't safe to push the battery that far.

Note that you can do exactly the same thing in reverse. If your phone runs out of battery and shuts off (due to the cell voltage cut off circuit), you can wait a while and then turn it back on. By then, the chemicals in the cell will have partially recovered, the cut off circuit re-enabled, and you can extract some more energy. The problem is that the cell isn't meant to be deep discharged and it will permanently damage. I'd be worried that the technique in this thread that circumvents the cut off circuit will cause similar damage, just in a different way.
[EVO 4G General] mrmomoman:
Glad you guys did the HTC Incredible trick :) It was first done over there when it was first introduced due to the battery not keeping a full charge as soon as it was pulled from the plug. Some think its a software issue of not fully balancing/charging the battery. It does help as it has helped on the incredible.
[EVO 4G General] pecosROB:
I must have done this about 50 times at least and it still takes close to a minute to go from orange to green when turned off... :confused:

[EVO 4G General] danknee:
All I want to say is that this process seems like a big pain in the butt and I have a much easier alternative. For $10 including shipping you can get 2 extra generic batteries and a charger on Ebay.

In my experience this external charger will get the battery completely topped off better than the phone's charger can do. Each time I use a battery off the charger I hold 100% charge for 5-10 minutes. When the phone is unplugged from the wall charger my phone drop 5-10% within 10 minutes.

These batteries and chargers and not 10/10 quality, but the charger works great and the batteries work awesome as back ups. Typically these ship from Hong Kong and can take 3 weeks to get to you. Unbeatable price though.

General search, price is usually $10-$12 shipped:

It's working for me too. Flashed the latest fresh rom and did this technique this morning and three hours later I'm still at ninety-five percent charge. Normally I'd be in the eighties or lower by now. I'm guessing that this is something we're going to have to do every time we charge though correct?
[EVO 4G General] nojive:
Can we please, please use the correct terminology!

I fly r/c helis/airplanes, and yes, you need to balance cells IF there is more than one cell. These are SINGLE CELL batteries (3.7v=1 cell)!! You balance a pack so that each cell is roughly the same voltage. My packs I use in my helis are 3 cell packs (11.1v) so I balance charge them so that each cell is around 4v or so.

I suspect that all this is doing is just topping off the pack, nothing more. If it works, great, but it is in no way balancing anything!!

Compared to the batteries that come with the Evo, how long do one of the generic batteries last for you? I was thinking of getting it and just switching them out throughout the day.
[EVO 4G General] DraginMagik:
is 10 a magic number, the exact number or just a number that will ensure all those that do not understand what exactly is happening will see results?

as a previous poster asked....is there something in particular we are looking for?
[EVO 4G General] intriskman:
You dont need to do anything 10 times.

All you really need to do is wait for the battery to hit 100% and then unplug the charger.

The problem is that, overnight when the battery charge hits 100%, it stops charging and runs of the battery.

In the morning when you unplug it it says 100% but after a few minutes starts dropping off at a very fast pace.

Just charge to 100% and then unplug it to get the same long battery life.
[EVO 4G General] EtherealRemnant:
