Okay...?
The majority of the people here have rooted.

It won't help. I have deleted the batterystats on mine phone more than 20 times in the last 3 days and there is no change nor hope!

Let me rephrase by saying your ROOTED phones battery stats might be lying to you.
And for the guy who tried it three times and failed. I don't think you took the time for fully discharging the phone. That's right I'm calling BS.
Anyway got to go my battery just dropped 30%

Just wanted to let you guys know that this is completely true in my case. The other night around 2am I went to sleep with the battery around 68%. When I woke up 4hours later for work my phone was turned off. I then plugged it in and my battery was at 0%.
I was on the perfect storm Rom. I then switched to das bamf. Still happens. Tried bump charging and 0-100 charging and its helped but when I reboot the phone the battery shows about 7% less then where it was.

I think that is thy the stock battery icons don't show an exact %, b/c they haven't been able to make it work right. Don't worry though i believe that the devs will get it before HTC.

Ok my battery was just now at 50%. I restarted and now showing 41%. I don't know what's going on.

As I said, you can charge and discharge all day long, it won't help!

Thank you for reposting this. So sick and tired of people complaining about dropping 10% in a few minutes after a full charge.

I think this is a glitch. It drops like crazy after restart but then stays there until it "catches up" I guess.

So far,I have only rooted my phone, not a custom rom. I either have a crappy battery life, which seems better when I shut 4g down, or there is a glitch on the metering. My .02 worth.

[Q] CM7 Alpha 6 on Sensation, poor battery life

Hi there!
so i decided to install CM7 alpha 6 on my sensation and ive been trying it it for 2-3 days (had alpha 5 before) and well the first day i recalibrated the battery after charging it to 100% and ... it went REALLY well!
i even Overclocked the phone with SOME kernel i found on the thread (sorry im not great with kernels or understanding them, i just know i use them to overclock but i made sure to know it was intended for CM7 use) and everything was still fine and dandy.
However i installed the radio that was suggested with the CM7 installing tutorial, not knowing what it did but i did it for compability issues i guess?, and the battery started shooting dead way too fast! like 1% every 5 mins or so. Now i read that the radio is pretty important for battery consumption so maybe by installing the new one i ****ed it up.
1) is there any way to revert back to my original radio? I live in Puerto Rico and 90% of the time at home i get EDGE because i dont get 3g here so i use Wi-FI calling and i do get 4g alot and good signal strength while not at home... the battery status displays my strength as yellow-green, 10% of the time its perfectly green. So maybe the radio i installed was an issue?
2) maybe its because CM7 still in Alpha stages and the battery isnt that great, or how is the battery for you guys? Did you mess with the radio?
3) Maybe its my battery i have an Anker1900mAh and it was doing just fine with ANDROID REVOLUTION getting 13 Hours of Medium - High usage during the day and i did do the 5 100-0% cycles throughout the first days... although i did clear the battery stats alot between the rom switching, maybe its ****ed with it?
i really like CM7 and i wanna keep giving it a try but if i dont get some options here i guess ill have to revert it back.
Sidenote: I also installed CM7 on my mothers MOTO CLIQXT and its been 2 days and she noticed that the battery is draining way fast as well. Didnt upgrade her radio though.
EDIT: i apologize for my terrible spelling and grammar

Also since I've been messing around with the battery stats and calibration this keeps happening and it won't show me the battery information. Any idea on how to fix this?

I am getting horrible battery life as well. I flashed their suggested radio. Gonna try flashing another radio and see if it helps.

i got a very bad battery life since i installed mike1968 3.6.0XE, a half day with the battery and then i have to charge it again. and i dont have wifi on or playing games, auto sync is also off. i like the rom but the battery life really sucks. i ordered a new battery and hopefully it will be better, it is the battery used for the Evo 3d.

Each time you change a ROM, you need to calibrate it by letting it charge to some 4.12v or so, and then let it discharge until the phone turns off. Try to turn the phone back on. If you can, wait for the battery to drain far enough such that the phone will NOT restart. Now charge the battery until it is 4.12v (not JUST 100% )
Do this a few times and youll notice better life. Also, WIFI DOESNT use battery that much when compared to data and phone calls. Use wifi whenever possible AND turn off anything that uses background data. Notifications and automatic reports/data collection all use data/wifi and will use your battery even when the phone is idle.
Check your standby current. It ought to be in the 10-50mA/Hr range. If its not, then you have rogue apps that ARE using battery.

Do you or anyone know what is the original Radio that TMO uses for the sensation (USA)?

Phone powers off when using camera flash

If I use the camera and have the flash on, and the battery is less than about 75% charged, the phone shuts off and won't turn back on until I pull the battery.
Often, when the phone powers back up after this, it shows the battery is almost dead, or at least significantly lower than before - I've seen it go from 70% to 15% a few times after this. It's done this with every ROM I've had, including stock Gingerbread and ICS, but it used to only do it if the battery was close to dead. Now I pretty much can't use the flash unless it's fresh off the charger or plugged in.
I'm thinking the battery is shot, would I be correct in this assumption? If so, can I use any Nexus S battery, or do I need to use a 4G specific battery? It's the Sprint 4G model.
Thanks!

If anyone cares, I got a new battery. Camera now works reliably, and I now get more than 6-8 hours out of a charge. Snagged the Anker 1600 mAh battery from Amazon.

While I was out today (about 3 hours), 4G was on, and I had music streaming as well. Running JellyBean (CM10 Experimental) with Air Kernel @ 1.2 GHz.
Think it's safe to say my battery was shot - it was a Sprint-branded battery that came with the phone, but I got it used, and the person I got it from last year got it as a refurb.

When was the last time u reset battery stats in the old battery since its supposed to be done at least every time u flash a new ROM or if in same ROM for some time do it about once each month....
And what ROM where u using and what camera ..... stock or market APP?

One of the Google developers came out awhile back and stated there's no reason to reset battery stats, ever. TWRP 2.2 doesn't even have the option anymore. Plus the phone kept powering off when I'd use the flash on the old battery.
I'm using Burns' CM10 Experimental (8/6) with Air Kernel, but I've had this issue with every rom, including stock (as stated in the OP). Problem happened with stock camera app and every 3rd party camera app, also happened if I used the LED as a flashlight. When it's happening across multiple ROMs, I think it's a safe bet to say it's a hardware problem.

..

The phone was a refurb that I bought used, and came with a Sprint-branded battery when I bought it. But yeah, I was basically asking someone to verify what I was thinking - which you just did.
Here's the battery it came with:
Anyway, several days on the Anker battery now, and no complaints at all. Battery life is easily tripled, though this screenshot was taken with me sitting on wifi all day. It seems to hit 70-80% about when the old battery would die. Remember I'm running an early experimental build of CM10, with a mild overclock.

[Q] phone shuts off before 0%

Hi, Is there any full proof method of fixing my phone battery so it shuts off at 0%?
My bacon shuts down at 8% - 4% usually.
and when it does shut down it blacks out. I don't get that pop up with a spinning circle saying you're phone is not shutting off.
Well, unless thats how the OPO shuts off by just immediately blacking out?
I checked to see if it was because my undervolt, so i brought back the voltages to stock, and unfortunately, the problem still remained.
I know you arent suppose to run these batteries dry, but it just irritates me that it would shut down at the 8% mark.
So any suggestions and fixes would be greatly appreciated!
Thanks

If you know that, then why the hell would you want to do it just so that you damage the non-replacable battery and potentially leave yourself with a brick?

The battery percentage displayed on your phone isn't exact, not at all, it's only an estimate based on the voltage level it's detecting at the battery. So if your phone shuts down at 4% it really isn't a big deal. If it's bugging you so much you can use a battery calibration app from the Play Store to try to re-calibrate the battery.
But, if you're letting the device get that low regularly, which it seems like you are, you're damaging the battery. You even admit that you're aware of this. So why do it? Running a lithium battery down regularly decreases its capacity, just like keeping it at peak voltage too much does too. So it's entirely possible that what you're experiencing is a symptom of your own bad battery usage behavior.

Gee, I don't know
Maybe I like to see a full screen on time, testing kernels and roms?
or maybe, I didn't expect my phone to shut down at 8%, so I wanted to see if it wasn't just a one time thing because the unknown piques human curiosity
Maybe as a newer model phone, I'm putting some faith into solid build materials from the phone?
My nexus 4 has been run down many times naturally being at school or work and what not, and the battery still runs like a champ.

Phone overheating - very poor battery life

My N5, running XtraSmooth + stock Google kernel recently started heating up a lot. Now I know its summer time and naturally it would tend to get hot, but my father's N5 is always very cool to the touch. Even in an air conditioned house running a stability test brought my N5 to temps as high as 86°, whilst the other N5 was just about hitting 50°. My battery gets notably hot too, and of course that hinders my battery life too. Does anyone know what's going on?

My guess would be you have an app/process running full wack on your phone running up the CPU and draining battery. Look at battery stat screen maybe that will help. Try factory reset and run it empty for 30mins or so (no account no apps) then set up one account and app at a time.

Android malware/virii are on the rise, and I was hit with something that did this but did not show up on the battery monitor of any app.
I strongly suggest an immediate full wipe and clean flash, as well as changing your passwords if you truly want to be safe.

Hey, I tried that earlier today but to no avail, battery stats look normal, Facebook is the only third party app that uses battery, but only 2% at that too. It's only kept the phone awake for 50s, and CPU total is 2m so it doesn't look like its Facebook, but my battery still idles at 40-45°. I wiped and started again from scratch but first I let the phone set for 2 hours to let ART finish carrying out any optimisations so the phone could cool down and perform optimally. Antutus stress test still ramped my CPU all the way to 80° whilst the other N5 hit 71° this time around, it quickly went back down and cooled off quickly yet my Nexus took forever.

Mines stared to do it too I'm on stock and ElementalX. I've hit 85°C and as it's still rising turned it off. I've seen a few reports of this. I've no idea what it is but suspect an app update. I've used greenfly and Amplify to lock everything down and it seems to work. Its at 52 and charging ATM. Until I did that I couldn't use the phone and charge at the same time

I just changed ROMs altogether, even after wiping I was still getting ridiculous temperature gains, more worryingly so for my battery. I remembered during winter to keep the phone cool I added adhesive copper to the battery and CPU, I applied thermal paste and made the copper thicker, I also *removed* the copper from the battery, since during summer time it'll only make things worse. That seemed to have worked since my battery isn't anywhere near as hot anymore. The CPU still gets very hot - around 80° still, but it seems to level out much quicker than before.
