[Q] Has anyone noticed battery life took a nosedive with the Gingerbread update?

Having waited months for this update, I was just as excited as many to put this update on. Unfortunately, even though it has fixed many issues it created a new one for me: battery life, surprisingly.
The battery life on my phone is now back to what it was at out of the package with all of the bloat and Froyo. All I did on my Froyo was root it, freeze all of the bloatware, and unroot it. The battery would go the entire day and then some with moderate use. The phone became very stable.
Fastforward to yesterday- the phone rebooted, so I had enough and I put Gingerbread on. Everything was fine yesterday, and battery consumption was great with all the radios on. After I woke up this morning from charging (USB), the phone felt hot. Battery Monitor was saying it was at about 101F (normally around 96F). I unplugged, and immediately the consumption was at about 250mA. Throughout the past few hours, it has gone from 150mA to 600mA consumption. I did a factory reset, and it didn't help. Nothing has worked yet to get the power consumption under control today. The primary things running are (not surprisingly) the bloat. Telenav I noticed was constantly noted as "Restarting". Appmarket gets force-killed, and it opens back up a split second later.
It might possibly be the data radio, as JuiceDefender can't even shut it off.
Has anyone found their battery consumption got worse with the GB update, and not better? Short of flashing a bloat-free rom on it, has anyone found a solution?

When an app constantly closes and goes into a endless restart cycle is what kills the battery the most. It also makes the phone hot. I had this happen with the NFL app a few updates ago.

After I updated yesterday my battery did also die fairly fast. I did a hard reset and now it seems the same as froyo. But I was one the lucky folks with almost no problems so I never rooted. From my understanding gingerbread suppost increases battery life mines about the same now

Guys you have to keep in mind that this is not the official release. LG either leaked this build out by accident or on purpose to quiet down the hungry stomach's that wanted a gingerbread build. Lets just cross our fingers and graciously hope that a more fresh and tasty build will be released.
For now just try and enjoy your phone. If you are having random reboots that are a little too often then try completely wiping your phone and then literally wait 10 minutes for the software to settle down, once settled then reboot and enjoy.

I was just about to make this thread. I've got from 100% to 38% in about 3.5 hours and it wasn't particularly heavy usage.

That sounds about right. There has to be a broken sensor or something improperly calibrated. It isn't warm anymore, but it is just gulping down the power right now faster than any device I've ever had. I have a feeling it may have thought it was fully charged. It was perfectly fine on the original charge left over from Froyo consuming only about 30-60mA. Overnight charge on Gingerbread? Getting this massive consumption. It was done on USB. Once it dies in the next few minutes, I'll do a full wall charge and hopefully it gets more than a few minutes.

You guys using the bloated version or the EB release with bloat removed?

My battery life has been fairly good so far.

Have you charged it since you ran the update?

I just plugged my phone in about 30 minutes ago and it went from 20% battery to 80% in 30 minutes. That seems very fast for the G2x. I really think the culprit here is it isn't charging properly. I did a factory reset already, and it didn't help.

I just got tired of disabling all the features that made my phone a smartphone, using juice defender...etc I decided to order an extended battery for $10 shipped off of eBay, 3500ma , I suggest u do the same.

One thing I have noticed is my Camera is apparently responsible for about 20-30% of the power consumption even though I've forced quit it and rebooted.

I am going on 14 hours now and am at 64%... light use, wifi on half the time, screen on for little over an hour. I have HORRIBLE reception at my house in ohio, the damn thing is usually just trying to hold 1 or 0 bars where i very frequently have dropped calls or text messages that go out slow or come in in packages because it finally found a signal again (aka my phone loves to spend juice looking for a signal)... I would say its pretty good and i used the hell out of it yesterday and killed it in like 6 hours so this is my second charge...

Luckily I'm in the second Category. I was on ultimate Rom and loved it but I just wanted to change it up so I rolled back to froyo. Then did the update, reflashed clockwork and charged it to 100%, booted into clockwork, deleted the battery stats, boot it up, pulled the charger and I'm on 15 hours now and still have about 20% left. I'd say they did something positive. I still need to freeze the bloat however. I'll worry about that later when we get a CM7 or EB build based on this rom that is stable.

After I turned off GPS on the camera and killed it, my battery life skyrocketed. Even though I was killing the camera, it wasn't helping. I had to actually turn off the GPS before exiting. I'm not sure if its coincidence, but I left it unplugged overnight and it used almost no battery.

Just for a bit of proof.. I took these after the update, in the one with the estimate you can see it only expected me to get 5 more hours of battery life based on the history, but it's going to last a lot longer I think.
All I did was wipe battery stats, charge to 100%, wipe again, waited 30 minutes, wiped one more time then unplugged and let it go. that was 17 hours ago.
I'm anal like that, I really did wipe the battery stats three times and let it charge to full again after wiping just to make sure it was maxed out. I'm a noob still so not sure exactly how the battery stats reporting works.
Oh yeah, this includes 1.5 hours of Order and Chaos. Streaming music from Google music for two hours while driving across town, 45 minutes of GPS while locating a business I've wanted to visit and about 5 chapters of I, Robot in google books.

[Q] [9020T] 3hrs of battery life, any ideas?

Ok, so i just picked up a NS i9020t and i get less than 3 hrs of battery life. i though this was rediculous. luckily my old samsung phone takes the same battery.
a few things. 2 nights ago, i had a fully charged battery put it in airplane mode, less than 3.5 hrs later it was at 32% left. wtf?
with a fresh reboot fresh battery, same day, from 7am-930am the battery was dead, that was with very little anything. a bit of web search, email check and 10 minute call.
so today i installed juice defender ultimate, put in a fully charged battery, set the phone to extreme defend. this is what i got, in about 3.5 hrs
display 32% (really, like checking my phone 10x for texts, checking a few emails)
cell standby 19%
android system 18%
phone idle 6%
browser 6%
voice 6% (one 1minute phone call)
Juice defender 4%
anyone have any idea what the heck is draining my battery???
i am using this rom
1ada25375426.signed-soju-ota-189904.1ada2537.zip (which i think is the latest) and my kernal is, 2.6.35.7-gf5f63ef [email protected]#1
baseband version
I9020xxkf1
aslo, ever since i have gotten the phone, wifi/bluetooth hasnt worked.
any help would be amazing..
also, i noticed while flashing a rom with full battery when the new rom loaded, i went to red battery bars. something really strange is happening to my phone right now..
j

hmmmm ... i hate to say this , are you battery for real ? i mean it is not a fake one ?
try check it if has 1450 - 1500 mAh capacity
be honest with you , i have no idea ... since i brought second battery , i do not longer worry about this ****
--------------------
flash kernel is same as you flash ROM via RECOVERY , but be careful with kernel's instruction , some kernel is only for some ROM such as stock , and some kernel is universal , compatible to all ROM

Try oxygen from, should be a software issue
Sent from my Nexus S using XDA App

they are both genuine batteries, it would be a very rare instance, i bought both phones used, one locally, one from the usa. same issue with both batteries, i shall try oxygen..

try a stable rom without any apps.

All of the above and also try undervolting, which saves energy for longer battery life. UV made the biggest difference in this department on my Nexus S.

General tips for saving battery on any ROM is to lower the Brightness(I know,duh)
Turn OFF Location services! All of them! GPS and also location using wifi...
Your phone is acting very weird, try flashing a light ROM, maybe it is so that your Battery Stats is screwed up, try re-calibrating your battery using this app -- Battery Calibration
Never mind Juice Defender and App Killing Apps...
Wifi/Bluetooth not working with stock? That's not right :|
Flash a new ROM, that's the best advice I can give you I guess...

Anyone having crappy battery life with ICS?

Just curious is it just me or does the Skyrocket have ****tier battery life running on ICS compared to it running on Gingerbread? Anyone else having battery problems. I've been running ICS on my I727r for 2 days now and the battery life is very questionable. Probably a battery stat reset will work :S

Yeah, my battery went out pretty damn quick yesterday, but that could be because I've been fussing with my phone more than normal.

The first day of using ics my battery life was okay. The second day my battery life sucked. Why? Because I set up Facebook. Battery manager showed 10% use and I hadn't even checked it. Its the bloat!

Same, my i727r battery life is horrible since i flashed ICS.
I have noticed that my android system is pulling a lot of juice compared to GB. I made some changes today like freeze all the bloat + installed UCLC4 modem. And wiped battery stats + complete drain and discharge of the battery. Lets see if it get better after a few cycles.

My battery seems a lot better! Way way way better. 25 minutes of web and its still full!

Battery has been much better for me with ICS.
Freezing tons of bloat helps..

My battery life has been horrible on ICS but when I look at the battery thing, Face Unlock used 35% of my batter (when my batter was 5% left) o-o it takes THAT much?

My battery life is absolutely amazing with ICS.
I have the stock rom debloated completely, and a lot of junk is disabled. Coupled with turning off auto brightness and leaving data off when i don't use it, the battery just chugs along.
This morning I got in my car at 7 AM, started playing music full blast through the stereo for an hour. Got to class, played some temple run, approximately a half hour worth. 30 texts or so, one 1 minute phone call. (data was off the entire time, it keeps facebook from butting in from behind) My battery has literally only gone down 10%, and it's 1 PM
I'm in love.

Seems fine here, I usually have it plugged in but today am testing it without. The couple charge blips are from when I had to get some files off of it.
I froze a bunch of the AT&T bloatware, have had Wi-fi, BT, GPS enabled the entire time. Moderate/light use... I've attached some screens.
I'm running http://forum.xda-developers.com/showthread.php?t=1567817 with the flashable ICS modem.

My battery has been horrible but it's only been a day for me and my signal has been fluctuating a lot on day one. It's stabilized now so we'll see after a few days of use. But right now it is horrible.

It seems mine is doing worse.
But I have been adding a lot of stuff since this is my first time rooting.
I am about to get a battery depleted(at 12% right now) and reset the battery statistics and install the OEM battery.

I thought there was a lot of debating over deleting the battery stats, i remember an article from a google programmer saying that it actually decreases battery performance...i personally stopped doing it a year ago and noticed a better batter experience, most of the time bad battery comes from a bad flash or apps that run in the backround and use location services

My battery life was horrible with ICS so im back to GB. At work with phone in pocket for 2hrs and was already down to 75% off killing battery and charging it fully next day. When I got home after 8hrs of work already at 50% and thats when its in sleep mode. Using it I would drain 1% every couple minutes definitly bloat. Might try new debloated ones but kinda skeptical since GB gives me amazing battery life.

Once the kernel source drops custom kernels will make all you guys stop crying your all used to optimized stuff not samsucks stuff lol give it time

Well condiering I have never reset them and did this first and only flash of the ICS leak, I'm hoping it helps out. We'll see what happens.
I have Juicedefender turning everything off while sleeping(set widgetlocker to deinied so when locked, widget locker stays active to be ready, and juicedefender see's that and turns off data)
On my 2100mAh nexus battery I barely got over a day(was getting 36-40 hours on GB)
Either way, I have two batteries so I'll deal with it until either an official ICS release or a new rom with better battery performance comes around.

I also have the nexus battery. Def have less battery life with this version of ics .
It could be the algorithm the use. At the start of the day is slowly draws down. As the day goes on it seems to drain faster

Actually, I have been having the Best battery life to date. I will post my list of APK's that I removed. I don't do FB or anything like that, so not sure if that is affecting it. Also, in a non LTE area. on the UCLA3 kernel, I was absolutely getting horrid battery life.

I live in an LTE area and I am getting almost a full day of use. Never got that with GB. I keep wanting to charge it, but I dont have to.
I do have Juice Defender running though, and it disables my data in 15 or 30 min intervals when the screen is locked. And I have SetCPU which limits the CPU to a max of 384 when the screen is locked.

Battery life bad even on Anker 1900!!! Help!!

Hi all,
I brought my HTC Sensation z710e about 14 months ago, and I'm a pretty heavy user, so battery life took a hit.
After about 8-9 months i got 4-5 hours screen on time on the stock battery. About 7 hrs heavy usage. I tried formatting the phone, and kept an eye on battery abusive wake locks, but to no avail.
To rectify that I've tried various roms (Elegencia 4, VipersS 1.6, Albinomans CM 10.1) among a few and also tried undervolting the phone. Nothing.
Then about a month ago, I brought a 1900mAh Anker battery which according to a lot of XDA threads is the problem solver for all battery issues.
I've been using that battery with Albinomans rom, and I have tried wiping battery stats to ensure the battery starts from a clean slate, but still I get barely 7 hrs, far from the promised 2days.
That leads me to conclude that something is wrong with my setup. And having tried many roms and kernels, formatting my phone and doing most other stuff suggested on the XDA threads, I cant work out whats wrong.
If it is a hardware issue, is there any way of finding out what it is, and what would be the way to rectify.
Any help would be higly appreciated
(although I've been and rooting and playing around with my phone for abt 3months now, this is my first thread on XDA. It may be a little unorganised in the way its written. If i've left any info out plz let me know. Thanx)
HTC Sensation z710e
Albinomans CM 10.1 10th May build

hello, if you use many applications that constantly require the 3G part of your mobile , it is quite normal ...
With my stock battery, i'm about 20hours and more but if i play games for a long time it's normal that battery drops.
I even think that you can be happy that your battery takes 7 hours using it a lot.
Try these CPU settings :
Governor Lazy or Badass
Min : 384Mhz or 432Mhz
Max : uses frequencies between 932 to 1188Mh
When u change ROM try to wipe battery stats before first start
Before u change the Kernel, make a Full Kernel Reset. Flash new Kernel

This part all rings true. You cannot measure the battery life by how long you go between charges. That's almost irrelevant information because if ti's set up properly the phone will use very minimal battery when the screen is off.
The proper way to measure the battery life is by how much screen on time you get plus phone talk time between charges. With an Anker on Albino's CM10.1 ROM that should be 3 to 5 hours depending on a few other things. If that 3 to 5 hours happens all at once, then you'll need to recharge in 3 to 5 hours. If you use it sparingly over 2, 3, or ever 4 days before you've use it for a total of 3 to 5 hours, then it'll last that long between charges.
The 2 things that use the battery are the screen's backlight and the cell radio. Those two things are the battery users. Bluetooth and Wifi are too. But theoretically you're not using bluetooth or wifi unless you are talking on a call or having the screen on. So you can still measure by the scren on plus talk time. And if you use bluetooth and wifi a lot your total use will be closer to 3 hours than 5 hours.

This part is not true. It has no effect on anything. And when you install any ROM the battery stats are going to get wiped anyway because you are replacing the entire contents of the system directory.
No amount of wiping battery stats, calibrating batteries, or any of that mumbo jumbo is going to help. It's all snake oil.
Also keep in mind that you do need to give a new ROM 3 to 5 full charge and discharge cycles before you really see what the battery life is like. If you're jumping from ROM to ROM every day to test battery life you'll never get an honest look at what batter life is like on any of them.

On albino's ROM? You only have 2 options. The one that comes with it, which is perfectly fine. Or SultanKernel, which isn't terribly different. But the install process of sultan gives you more configuration options.

[Q] Heavy battery drain issue - help troubleshoot

Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:

How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.
Go here:
http://forum.xda-developers.com/showthread.php?t=1179809
Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.

Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.
