I just got a new battery for my phone from t-mobile and want to make sure to charge and break it in right from the start. I currently own a G2X and am a rookie when it comes to knowing about kernels, roms and etc (i have been studying little by little). I have a somewhat good understanding and have tried a couple things to get my battery life right.When I first got my G2X, I played with it right out of the box for about 5 minutes and the battery was at 30% from about 35%, then I only let it charge to about 80% and had to leave. I have ONLY had one good day of battery usage and that was after my first day of using setCPU & being rooted. It is currently rooted using the unlockr tutorial, "setCPU" from the market and have only one profile for "screen off" 216min-456max. I have read at least 70% of the battery threads about my phone already. I turn off gps, wi-fi and have screen brightness set to auto. Also I have deleted qik video, t-mobile account app and all the other major bloatware that comes with the phone but still get bad battery life. If you guys want, I can post a picture of my juice plotter battery stats. Please help me out i'm looking to bring in my new battery the right way or fix my old one and have the new one as a spare.
Edit:I put this in the wrong thread. excuse my noob/rookie mistake lol. sorry
I am very sorry to open a new thread about battery drain that has been discussed so many times but I am really desperate.
I recently purchased a second hand Nexus S i9020A (unlocked AT&T version) from swappa. (Website that sells only android phones) and I am getting terrible battery life no matter what I try.
The phone is rooted and have tried several ICS roms and all have terrible battery life about 6-7 hours when the phone is on idle for most of the time.
I then installed CM7 as I read that ICS has some battery drain issues, but I still get really bad battery life 6.5-7.5 hours again the phone is on idle for most of the time.
I also tried several kernels.
I tried disabling the WIFI, GPS etc this did not help.
The phone came with two batteries an Anker Battery and the Samsung battery. I sent Anker an email asking them about the battery life, they told me to let the battery discharge to around 10% and recharge to 100% a couple of times. I did this twice, but no improvement in the battery life I was about to do it a third time when I fell asleep the battery must have drained completely and now that battery seems to no longer be working.
I thought maybe I am really unlucky and I got two bad batteries, so I purchased a new RND Battery from Amazon as I thought maybe there were some problems with the Anker. Turned off the phone let it charge for 7.5 hours, but the battery meter still showed that it was not fully charged, but the instructions said to charge for at least 5-6 hours, so I turned on and unfortunately I have the same battery drain.
I have installed a Battery Calibration app from the Android Market to see what the reading was and when the phone read 100% charge it was a little over 4,000 mV . I am not sure if this is what it is supposed to be, maybe one of you can let me know.
In addition I have wiped the battery stats from from the bootloader a few times after I have fully charged the battery and even factory reset the phone but this made no difference.
Last night I even flashed a new radio I went from I9020AUCKF1 to KB3 but this also made no difference. I have been struggling with this problem for about a week with no improvement what so ever.
I read that its bad to completely discharge Li-on batteries, so before I left home to go out, I turned off the phone so that the battery would not discharge, when I arrived home a few hours later the battery was dead even though the phone was turned off. (this was the original Samsung battery not the new battery I purchased, I did not try this with the new battery as yet)
I checked the battery usage and compared it to a Galaxy S2 to see what was using up the battery and the OS and Screen usage % seems to be comparable amount to the GS2.
I also tried a few of the Governors that are included with CM7 and also used the wheatly Governor when I was on ICS, but it made no difference.
Can any one help me? Is there something wrong with the phone? I purchased this as a present for someone who really wanted an iPhone because I could not afford an unlocked iPhone and they are really disappointed by this. I know this may be an isolated case, but I always assured the person that the android phone can do everything the iPhone can do, but not I feel like such a fool.
Can this be fixed? I purchased this when I was in the US but now I am away so returning it would be a problem. Is there a way to check if there is something wrong with the phone itself that's causing the battery to drain at such a fast rate?
Any one that can help me I would really appreciate it and be very thankful, I know there are other topics that deal with battery issues, but I have been researching this for about a week and tried everything I can, I didn't just start a new thread without trying.
The screenshot below shows a high display usage because I was using the phone to try to troubleshoot normally android system uses the most and display is closer to 7% but the uptime is the same. Even though it says 3h 51 mins at 48% in the screenshot the battery seems to discharge faster as it percentage goes down.
Can you enter this code and check for battery information:
*#*#4636#*#*
You can check the battery health and temperature. It might give you some insights.
Do you have good reception? Is it constantly trying to connect to 3G networks? Can you check apps which might be trying to connect to Internet all the time? Do you have this problem once you flash a clean rom (or maybe it starts after installing apps)? Have you tried stock ROM?

I've read about this in other threads... not sure if I've already tried it... ull need to do a factory reset to wipe all data and battery calibrations. Once u reset... flash Evilistos ICS rom 4.0.4 and use the Air Kernel 3.0 .... flash the Tweaked Nexus Boot Animation (looks really nice but you don't need too lol) and that should do it... =]

Hi Oogway first of all thanks a whole lot for your response.
I dialed the number and got the following
Battery Status : Discharging
Power Plug : Unplugged
Battery Level : 100
Battery Scale : 100
Battery health : Good
Battery Voltage : 4096 mV
Battery Temp : 34.0 C
Battery Technology : Li-ion
Time since boot : 9:58
Just finished charging it again.
I have good reception, but I have no data plan on this phone so it isn't using any 3G, actually I don't even have 3G in my country :|
I have no apps installed and the problems still happen even with a clean install. Before the person shipped the phone to me I asked them to install the stock rom and when I got it the problem was present, since then I tried different roms but to no avail so far.
Thanks very much for your time and effort in offering possible solutions, I am grateful for your help.

Hi iGoogleNexus, I tried the factory reset and battery calibrations, but did not try the ROM and Kernel you suggested, I will try that. Thanks very much for the suggestion, I will let you know if it works or not.

Its not a new phone its a used phone, but the seller has agreed to refund me if needed, the problem though is that I bought the phone in the US but I am not in the US now, if I return it to him he may be charged taxes etc.
I returned the phone and radio to stock, but it seems the issue is still present. Any more ideas?

Tried this, but no difference.
Did you buy through Ebay? Perhaps you can print out your receipt and get a warranty repair through Samsung. That's what i did when i deleted my imei. Cost me nothing except postage.

I have abyssmal battery as well with my used i9020t. Although I have only used various ICS so far and don't know how used the battery is.
At night I put it to airplane mode and closed running apps. In the morning the phone feels warm and battery drained drastically, which makes no sense.
I just got an Anker battery as well and will try some Gingerbread rom. For now I'm using Franco kernal and undervolting by 50mV which help a bit, but not much.

Hi Bedalus, I bought it on swappa. I bought a few phones there before without any problems. I have a paypal receipt from swappa, maybe I can email samsung and find out if they can repair or not. I honestly think its a hardware issue now. Because the battery still drains even when the phone is off. I flashed several radios and roms, wiped battery stats, changed battery, wipe data and factory reset and its all the same.
My issue though is that I am not in the US and the phone was purchased from the US so return may be a problem as well as shipping to Samsung, but I will email them to find out more.
But thanks for your suggestion Bedalus, really appreciate it.

Hi Ekasol, does your battery drain even when the phone is off like mine? How much battery life do you typically get? I get around 6 hours. Just to let you know that I did flash the stock ROM on the phone but it made no difference to me.
Mine is the AT&T version, I got the roms here .. http://forum.xda-developers.com/showthread.php?t=1445621
But you can get the roms for yours here http://forum.xda-developers.com/showthread.php?t=1063664 in case you have not found the original roms yet. Best of luck, I hope at least one of us is able to get the phone working or repaired.

Bedalus, before I contact Samsung, do you know if rooting and installing custom roms void the warranty?
Technically yes. However, if you wipe, install a stock rom and bootloader and lock the bootloader afterward, they have no way to tell.
Thanks Harbb
Can you try this Gingerbread rom NSCollab anyway, I know you said you tried GB already. I don't have time to test with full battery yet, but Gingerbread seem to retain battery life pretty well.
If you still have time, I would say save yourself the hassle and return it, it sounded like hardware issue. And buy the person an iPhone instead. If he/she is not tech savvy it is pointless and will just give the person a difficult time. I do not have an iPhone, but I have to do iPhone tech support for my co-workers, Android would just be a nightmare.
Also if the person don't mind going with T-Mobile, see if you can return it and get a Galaxy S 4G. It is one of my favorite phone. No LED flash and ICS (yet), but you get microSD slot and HSPA+ 21Mbps (cheaper plans too). And best of all the Valhalla roms.
Tried NSCollab, battery drain seems to be a little worse with this ROM. The reason I did not purchase the iphone is because of the cost, I got this for around $260. Thanks for the suggestions though, I will consider them, but so far it looks like this phone has some hardware problems.
LET'S MAKE A BETTER BATTERY LIFE FUTURE FOR ALL
I thought I would start this thread for our phone. I have the AT&T HOX, but any carrier that uses the msm8960(Snapdragon S4 Dual Core
chip) should participate. Sorry Tegra 3, different chips different, battery concerns.
Basicly, I just wanted a place where everyone could
report there battery life, things there doing to get it(if good or bad), and fixes or ideas to increase battery life. This way everyone can
benefit from others knowlage and experiance.
I personally just got my HOX as a replacement for my broken SGSII, and as it is a
refurbished device, I am having a few concerns. One being that my battery life is horrible. Its been on average draining between 20
-30%/hr. So, at the advice of another member I got the better battery stats app and checked it out and found that HTCDm was the
process preventing my phone from going into deep sleep(better battery Stats has pretty good documentation as to how to use it, if you
choose to use this app just read the documentation. It is short but precise). Upon further investigation I found that that process was the
one that checks for firmware updates and throws the message about "there's an important update for your phone". I didn't want it
yet(because of the no root issue on 2.20 and I haven't unlocked yet because I want to make sure that everything is okay with this phone
before I void the warranty). I'm not sure what else HTCDm does besides the firmware update check, but I froze it anyway with TiB and it
drastically increased my battery life as my phone now properly goes into deep sleep. :laugh: But all is not perfect yet, as my phone still
drains at about 20 – 30% per hour when the screen is on:crying:. I'm not sure if it is a battery issue and I am about to call AT&T right now
about it (it really sucks that they can't send me a new battery because it is not removable). But that is just me. If anyone has any
suggestions for me, I would love to hear them.
:fingers-crossed:SO EVERYONE PLEASE POST: :highfive:
YOUR BATTERY LIFETIME
ANY PROBLEMS YOU'RE HAVING WITH BATTERY LIFE AND NEED HELP WITH
ANY PROBLEMS YOU'VE HAD AND THE STEPS YOU TOOK TO CORRECT THEM
ANY PARTICULAR APPS OR TWEAKS YOU'VE USED TO INCREASE BATTERY LIFE
(OPTIONAL\IF YOU CHOOSE)
NUMBER OF APPS YOU HAVE INSTALLED (ESTIMATE)
GENERAL NUMBER OF ACCOUNTS AND THEIR SYNC SETTINGS
WI-FI AND DATA SETTINGS (AND ANY TASKER PROFILES USED WITH THESE, ETC.)
ANYTHING ELSE YOU CAN THINK OF OR WISH TO LIST
P.S. You can Post more than 1 vote in the poll, 1 for normal use and 1 for heavy us. This should give us a good idea of the average battery life across all sorts of roms, kernels, setups, ect.
"TiB"?
Root and don't use a sense rom. Sense is okay, but it drains battery a lot (has been improved with 4.1 but still...). Also get rid of or freeze apps you don't use and/or don't need.
Oh and TiB stands for Titanium Backup I'm assuming.
I'm on 2.20 which I got new, and I disabled as much bloatware as I could. I can go a day from 100% in the morning to ~8:00 with 50% left. I use my phone for browsing XDA, texting, and playing a game or two. I consider it okay battery life, and I'm on stock! Trying flashing a different rom and see how the battery life goes.
We should do a poll with screen time instead.
Mine is 2-3Hr screen time (auto brightness) with heavy usage.
Total time on charge varies from 4 hours to 24 hours.

Hey rye-rye! Stopped reading after the second paragraph because I realized this is redundant B.S. but thanks for the incentive. We already have a battery stats thread. :beer:
OOPS!
Sorry that, Isert and could not find one nor did it find one I was creating this thread. I was actually just coming back, because I just got the chance, to update the OP post with a much more detailed breakdown of what I was expecting from the thread and also I was going to delete out all of the stuff about my replacement and yada yada yada because I managed to get all of that fixed and Done and not only that I was also going to post in detail my success story of how I went from 3 to 4 hours battery life to on average 9 hours with moderate use. And as of yesterday I set my all-time record with 6 hours and 5 min. to go from 100% down to 6% battery left. What's that you say? That's not very good for your all-time record! And you would be correct but I haven't told you yet that I was actually on the phone with the screen on using it to make phone calls surf the Internet on Wi-Fi and LTE as well as running various apps downloading new apps and checking them out. So in total the on-screen time was around 5 hours and 45 min. with about 15 min. of sleep. so is the official battery. The one that I just saw on the 1st page that says "battery stats XL", I believe? If so I'll just make my post in that one.
Friends,
I've rooted my S6; pluggend and unplugged it from the fast charger over 100 times within minutes. Drained the battery to 0% over 20 times and flashed a number of ROMS and BLs and Modems without paying attention to Model number and CRC. I believe my S6 is fully raped now and won't recover. Battery life is horrible and it's acting up big time.
Any ideas on how to salvage the phone?
I read you shouldn't drain newer batteries to 0% because it will affects its battery life. Best thing you could do is keep the phone between 40% and 80% battery.
As for recover, put your phone in downloadmode, download your region ROM and flash via Odin or perhaps via Smart Switch.
Good luck

never understood why would you root your brand new phone. If it gets older and doesnt get updates anymore then its ok but otherwise just nah....

rooting is not just about updates its a big misconception ,rooting gives you the full privilege and a super control over your phone, almost all experienced xda users are so used to root and its privileges that they just feel like stone age on stock roms ,root it removes a number of restrictions and allows you to mould your phone as you want and not as the OEM wants! I rooted my nexus 5 on the second day of buying and never ever unrooted it !

This is exactly why companies don't want us to root phones. Most users don't understand what it does.
I understand exactly what Root can and can't do and it is simply not needed in this day and age. It's like souping up your Vauxhall Corsa to zip around looking good. It's still a Vauxhall Corsa and it's not going to do any more or less than it did before.
Rooting is a dinosaur from a bygone age you needed when Android was so crap you had to do it to have a working phone. These days you get zero battery improvement, zero performance improvement and zero need for extra storage or removal of ads as we have everything we need without Root.

You need to chill first!
All you got to do is
-A wipe data
-Flash stock firmware from odin of your region
-Callibrate your battery
-Use your phone normally and take precautions next time while rooting and flashing
What may have caused battery drain:
-Unstable kernels!
-Modems of different region face problem in signal reception hence drain battery
-poor calibration of battery due to continous flashing which causes sudden jumps of battery

I have been going back and forth on rooting. I have a Sprint s8+ and know I don't have a full bootloader unlock. So my question is, are the modified stock roms such an improvement that you would endorse rooting over just running unroofed? Was there ever a resolution to the wierd battery thing going on? Just looking for some help from our XDA community.
Thanks everyone.
I used a lot of different custom roms and found there was no real improvement in battery life.
Now i use Light rom for about 3 weeks and i really have a outstanding battery life on this rom, it's super smooth and with GPS and Bluetooth enabled whole day (for my gear S3) I still have about 55% battery left at the end of my day with 3 hours of SOT
