Battery issue?

Purchased this morning and the battery was drained... Fully charged at 5:30pm. Now at 7:30pm im as 50% with minimal use. a 4-5 hour battery life is not going to cut it.
Hopefully this is just an initial charge issue, but my vibrant never drained this fast.
Worried!

U may actually have a bad batt. But id give it a chance. Drain it down to 0. Turn it back on. Let it die again.
Then charge it while off. If it happens again youll know.

Don't worry man, it is because of the first charge.

I have done a few charge cycles completely draining it and battery life is still pretty bad...it better get a lot better than this or it is going back.
Also getting random freezes and reboots.

I've got a ton of apps and widgets installed and use Exchange push. Battery life has been just a little worse than my G2. The phone froze after I first configured it and I had to do a hard reset and rebuild it. It runs a lot better after the reset. You might want to start-over and see if it make any difference for your freezes and resets. I'm purely guessing it may be the difference between the phone configuring the SD card and reading off of one that's already configured.

Bad batt. 4 hrs is a wayyyyy bad.

Sounds like my experience too. My battery yesterday lasted me no more than 7 hours. Wooh, I was pissed. So far today though, It's been on for 14 hours and I'm only down to 25% with some medium-to-heavy emailing and texting, and a few 5 minute phone calls. I'm very impressed after this second charge. I'll drain it again tonight in hopes for a little additional life. Stick it out for another day or two, OP.

I'm really concerned because I've had my phone since Monday and have charged it at least twice a day. It's not getting any better :-( I have even froze alot of the bloatware and apps that run in the background. I can't handle 6hr battery life :-(

You mean for an exchange? Or ask for a new battery? Will they do that?

I also have serious battery issues. The battery usage is mostly consumed by cell standby and bluetooth. On my mytouch 4g at most these parameters were a few percent each. On the g2x they are like at 25% usage each. This does not appear to be normal. This is with minimal to no usage. I dont get it. Is it a software issue, there is no reason cell standby and bluetooth should be usaging so much juice with little to no use.

Root your phone, after that install Titanium Backup from the market, and once you load titanium backup, you can actually go to Backup/Restore and find the app that you want to freeze, click on it and choose Freeze.
Once you install Titanium Backup - it will ask you for root rights - click on "yes" or "allow" (dont remember exactly which one it was" so you can provide root rights for it.

Anybody know of documentation on best way to calibrate the battery? I did 1 discharge - charge cycle... how many more do I need to do? Do they need to be back to back or can I keep it plugged in while using it today?

My battery lasts a little less than my NS or vibrant. It should at least give you 5-6 hours of HEAVY usage. I left the house yesterday at 10 and by 6 it was done. Since it's a new unit I used it heavy, plus I rely on it for scheduling and contacting clients about every 30-60min. I was also playing games on my breaks.
You probably have a bad battery.

I do seriously think that there are a lot of improvements that will come in a software update. The Cell and Wifi usage are ludicrous and it's probably a matter of getting the phone out the door with an update to follow.
This is only the second Tegra 2 phone to be released in the US.

2nd day with the G2X and the battery life isn't getting any better... If anything it's getting worse...
90% at noon and 20% at 2:40pm. Plugged in at 2:40 and now 20 minues later im back at 88%
Drains way too fast, and seems to charge even faster...
This phone is faster is every way compared to my vibrant, I just wish this wasn't true for the battery loss..

Battery draining AGAIN

So i tried what you guys suggested. I rooted the phone, bought setcpu, using anttek to freeze running services, and used the battery calibration app still NOTHING. I just woke up and my battery was at 0 before i went to sleep it was at 62%!! How can it die in idle with no running servislces wi fi off gps off BT off i mean it has to be the battery right?

I was just getting on here to rant about this. It seems that whenever I use the phone the battery gets warm and declines quickly. Lost over 40 percent battery over 2 hrs mostly playing mp3s

This may or may not be related...just something to think about. For years I've placed my phone in the top drawer of my nightstand when sleeping. What I noticed when switching to Android is if I leave syncing on it will drain my battery. My theory is...in the drawer my data signal is very week or non existent. The phone dutifully tries to sync on that weak signal...searching for signal...fails and retries...or succeeds and transfers at a snails pace. Result dead battery. I've found that disabling data before bed results in less than a five percent drop. Just my experience.
If not then I'd suggest a phone swap.
Also...Why in the world did you start another thread? If we scatter all these x is wrong with my phone posts across multiple threads it really hampers the effort to solve the problem.

I've also noticed this. In the morning my battery life is decent but by the after noon I can do light web browsing (10-20) mins in an hour and loose over 15% tmobile told me that isn't good lol I have a new battery on the way. They shipped it out yesterday we'll see if that helps. Also my battery was dead when I got my phone did anyone else get one that couldn't even power the phone on?

Yes. Like the OP, I tried the solution of the person that is so called getting 20hr battery life under medium usage. Just doesn't seem feasible at all. And its really annoying to have to cut the data off completely to keep the phone from getting warm...

If you researched the problem and tried the solutions offered, then the logical next step is to contact T-mobile for a replacement. This is an early release of a new phone; there will be defects. And you don't have to settle for a defective device/battery. I can assure you, I get battery life on par with my previous phone (8-20 hours depending on my usage)..so, bad battery life isn't a problem inherent to the phone. And my phone doesn't get warm with data usage. It sounds like you might have a defective battery or phone. If you aren't satisfied, don't settle...make 'em make it right.

I get about 5-10% battery drain overnight most nights and I am not mindfull of what apps are running or what is on. My experience obviously differs from yours. I do get great service in my bedroom where the phone is overnight. The other night I did experience a bout a 60% drop when I left the phone in my daylight basement (underground). I get crappy 2G service in my basement and it looses signal a lot. I think it adds some credibility to the searching for service slowly killing the battery. maybe try putting the phone in airplane mode before going to sleep. That should give you some indicator.

I'm now are 28 percent after 3 1/2 hrs with the display only using 13% if that..

Just curious, does your phone feel hot right now?

You might have a bad battery or something. My first g2x rebooted constantly and drained the battery and got hot.
New one goes 8am to midnight with 20% battery left, on moderate usage. And even at the 20% left i can leave it overnight and it'll still have power in the morning.

The phone is going to get warm is use because the CPU is under load and that produces heat. As long as its not overheating this is normal.
Have either of you tried the factory reset? That fixes the idle drain for most people.
Also... Your phone is going to drain battery faster while actually in use no matter what you do. The LCD and data connection are the biggest battery drain for smartphones. Until battery technology improves, there is nothing that can be done about this. But like I said try a factory reset and you should see your idle drain improve dramatically.

Were you on wifi? Because if you weren't that much drain is within the norm. Web browsing = constant data connection = more power consumption = faster battery drain.

I had 10 hours of heavy use yesterday and had 25 percent left... 2.5 of those were in airplane mode cuz I was flying from Phoenix to Atlanta but I watched a movie during the flight and had music playing the rest of the time... during my layover which was 4 hours I browsed the web, watched a stream of the Celtics vs heat for a bit, more music... I plugged back in with 25% left and had 3h20m of screen on time... this battery is freaking awesome! I had drain issues initially but they went away and now I'm golden

when i did a factory reset, my phone was getting hot until i remember about the *#*# thing and changed that to wcdma/gsm auto. then my battery life got better.

Get juice defender. Its work wonders for me and my buddies thunderbolt actually makes it through the day now

Battery Drain is mostly Cellular radio
I too am have been looking for a way to have this phone last at least 8-12 hours with normal usage, but I don't think its going to happen unless there's some major update to the radio firmware coming in 2.3 Gingerbread..
All the evidence seems to suggest two culprits... for battery drain.
- First is the 4G radio, look around at almost ALL 4G enabled phones (whether on GSM at&T Tmo or Verizon), all eat your battery, from the very beginning EVO 4g, Verizon Thunderbolt, Mytough 4G every single one of those phones has the users complaining about horrid battery life. You can confirm this by looking at the battery usage on the G2X and you'll see that the number one use is Cell Standby (that's the cellular radio) on my phone its anywhere between 35% to 60% of total power used.... on kmy nexus one it used to be the display.
-Second, Tegra 2 is more power hungry , granted its a mobile SoC but its mainly designed for Tablets and such with beefy batteries, this is the reason that the Atrix comes with a 1950MaH battery, you can try and use SetCPU to lower the speed, but I have had minimal success.
Here's a test , when you don't need your phone put it on Airplane mode, for 24hours and watch HOW LITTTLE the battery drains.. reason the cellular radio isn't on..

I agree. These battery threads are driving me nuts.
Go in the other million threads and read

The thing that is strange to me is how quickly these phones charge. It seems to go from 0% to 100% in well under an hour. Was thinking I should try charging it while off (well, screen w/ battery only).

What???? Having the phone on makes my battery drain? WTFO?!?!?!
Seriously though, I have not experienced bad battery life on this phone. Last night I left my phone off the charger, gps, wifi and wifi calling on, and when I went to bed at 1030 I had 64% battery. At 700 this morning I had 54% battery. Only a 10% drain for me overnight, or a little more than 1% per hour.
All I've done to achieve this is the following (and I realize that supposedly you no longer have to condition Li-ion batteries):
-when I got the phone, I didn't charge it but instead let the battery die completely to where I couldn't even turn the phone on.
-charged the phone overnight w/o turning it on.
-let battery die completely again.
-charged phone overnight w/o turning it on.
-let battery die completely again.
-charge and use phone normally.
I've also rooted the phone and used Ti Backup to remove most all of the bloatware except wifi calling, but otherwise it's the stock rom.
I typically get an entire day of my normal use on this phone. If I use it alot, I have to top off the battery w/ my car charger on my way home from work. This isn't unusual. I had to do this w/ the blackberrys I owned and my evo when I was on Sprint. The battery life doesn't seem any better or worse for me than any other smartphone I have owned, and it's certainly better than my evo or my wife's evo, and both of those were rockin' custom roms and uV kernels.

Mine is more like 7%/hr, which is totally unacceptable, I have all sync turned off, except exchange... with my HD2 running Froyo, I could do 2%/hr with the same settings.... I am still trying to figure out what's draining my battery...
I have also noticed high data usage.. I've tracked it down to T-mobile's AppPack. I've never used the program but it's constantly draining away my data... Is there a way for me to remove the app or disable it?
Thanks!

Get Watchdog from the Amazon appstore to find out what's draining your battery. I believe it costs, but it is a thoroughly useful app
Don't think we can remove carrier apps until we have root...that said, you could try adb pull, but I'm not sure whether it will have any effect. May need root for ab pull, in which case we can't get rid of carrier apps :/ sorry

please post how many charge cycles you went through, its important.
I am personally using HD2 and battery live is amazing. and its only 1250

this has the best battery life ive ever saw. I'm in 0ma all the time the phone yesterday lasted from 530 am til 7 pm at night with a lot of text and playing games like homerunbattle 3d. If you play that game you know how much of a battery hog it is. Best battery life. Battery was soo good i barely charged it went to work with a 40% battery and it easily made it through a day with moderate texting all day!!

Gotta say... coming from a TBolt this thing is like sex in a tin can.
Idle is 1-2%/hr probably. I would get 10%+ on my TBolt at times... if not more. It was bad.

today is the first time I'm having issues. Only 4 hours since charge & down to 40%. The Awake time shows as 99% of Up Time. Is that normal??? Also, anytime I look at the task manager it shows wifi calling running even though I have it shut off

I've got an Asian model sensation (ie. 3g and not 4G model ) and I find my battery isn't really calibrated properly so its hard to comment on average percentage drop per hour. I've recharged my battery 3 times already and i find the battery stays at 100 percent for around 30 minutes of constant on web browsing, then it will drop at a rate of 10 percent every half an hour with constant use and will fluctuate.
To report on a rough usage breakdown, with all background syncing disabled, I managed to get 10 hours standby before my phone dropped below 10 percent. This was with 5 hours of screen being constantly on doing mainly web browsing on 3g and one 15 minute phone call using my wireless Bluetooth handsfree.
I can report the battery life with constant usage is better than what i got with ny hd2. Running android ROM, it used to do around 3 hours of constant web browsing before the battery will fall under 15 percent. In standby my hd2 used to drop around 1% per hour, which was quite excellent.

Those are the stuff I'm talking about, it appears that one of the settings and/or app is constantly using the processor, which causes the phone to stay awake even when the screen is off... I just haven't figured out which app is causing the problem.. I am suspecting it is one of the Tmo apps.

I'm looking at a full battery life of 11 hours, 49 minutes with moderate usage (some calls, decent amount of texting, some games). I use the app/widget "Battery Left" to do its own independent assessment of battery usage and life.
So far the battery reminds me of my early days with my Nexus One -- before I had it rooted and optimized and undervolted. Once rooted and optimized, I saw a good 50% increase (at least in battery life).
If you'd like some relief right now (before we get it rooted), I recommend Juice Defender on the market. It turns off data (among other things) every now and then to save battery, and with this I can squeeze out 18+ hours with moderate usage.

how are you checking the percentage? when I looked in the settings menu, all I see is a long green battery bar, no actual numbers. Or are you all estimating from that?
I don't monitor my standby time, but I'm sitting at what looks like 40% after 13 hours of fairly moderate usage during the day, I'm impressed.

Ive been getting about 9 hours out of a full charge. Had to put my phone on the charger today at around 4 o clock because it was dead. I dont have much more info other than that. I will keep an eye on my processes over the next few days. I have only 3-4 cycles on the battery though.

To check the percentage of the battery life u have to download some battery widget in the market.. I.e smart battery monitor or battery percentage s.th like that...
Sent from my HTC Sensation Z710e using XDA App

You can also check battery level by opening Phone and dialing *#*#4636#*#* and then select Battery information.

I'm using Juice Defender and I have to say it really does the job : my Sensation lasts More than one day and a half (30min calling a day, texting, Android Market, Angry Birds...). Without the app running it would last a day (Angry Birds drains...).
Juice Defender says it is increasing battery to 1,53% and it is very close from reality.
I've been owning the phone from 24th of May.

Expected SOT

Hi,
recently I bought N5 and I am very pleased with it. I could say that I love it. But I am worried about my battery. When I was buying it, the dealer at my carrier store, was hiding the box when opening it from me. I think that the box was not sealed any more ( i dont know if it is only in my country but here it's usuall that when buying a new phone they cut the sticker on the box infront of you). When I called at my store they said that they had only one more. And I am worried that the phone was used befor me for showcasing in the store. My battery usually lasts for two days ( I also have N7 so when on university i use N7 for heavy work) but barely get 3 hours of SOT. Wifi and 4G mostly off and brightness at minimum or max at 30% if on sun. Assistant of, gps of, ART on, using snapdragon BatteryGuru. I would really like to know what SOT should I get with this settings. And if you guys think I should go for warranty and hope that they replace my battery. Is there any way of seeing if the phone was already factory reset? Also I saw guys getting 5-6 hours SOT with wifi on here on XDA. Don't get me wrong I love the standby time but when using it (FB, twitter, messaging, browsing Chrome, 2 mail syncing) the battery drains like F1 car drains gas. If this is somewhere answered close the thread and point me there . Thank you

screen on time is totally dependent on personal usage.
the best thing to do would be to root it and install 'better battery stats'. then you can analyze your battery properly. feel free to let this run for a full discharge and then post your screenshots

Yeah the problem with SOT is purely personal and that is why I posted here to see what you guys think. But still it is interesting to see how different the time can be from user to user. Will post screenshots in the evening.

remove this. It doesn't help and if anything, it makes it worse

The battery drains whether the screen is on or off. If you're getting two days of use with 3 hours sot I would say that's ok. You might get 5 hours if you drained the battery in a day. Does that make sense? It does in my head!
Sent from my Nexus 5

Ok so I removed Battery guru. And here are my stats from today (this was not my normal day of using it). Through the day the screen was almost constantly at the same level of brightness. And a lot of wifi and even 4g usage. But my battery could be draining a bit faster too because of not that good cellular coverage.
As pepdavies said with my normal use probably I would get closer to 4 hours if I would draind a battery in a day. .
Can I aske one more question? If I charge my phone over night and phone is off, will it overcharge my battery the same way as it would if it was on?

ive always charged my android devices overnight while they are on, nothing bad comes from it. you will be fine. i do it on my nexus 5 every night, yet still see at least 5 hours sot every battery cycle(5+ hours sot because i use lte exclusively, it gives better battery life than 3g/2g).

You can leave the phone plugged in 24/7/365, on or off, and it will never overcharge, whatever that may mean. Nor will it overheat, slow down, melt, or explode.

I got 7 hours of screen on time by having the screen on a low brightness but that is only practical in a dark environment. I've also disabled a lot of google stuff and uninstalled google+ which was destroying 20% of the battery regularly. Generally 5 hours of screen on time using lux to lower brightness levels but to a point where the screen still looks nice

4 hours sot is typical for stock

i dont really see how anyone can enjoy using there phone at minimum brightness unless its in a dark room i keep mine at 25% and it looks damn good using a tweaked gamma profile. Regarding battery i average 4.30 hours screen on time and 23 hours total with wifi only mostly web browsing and as said already there will be no harm in charging your phone overnight when i wake up its at 100% and battery temp is at around 24c

you are right that it will never overcharge, it is not optimal to keep your device with a full charge of battery for an extended period of time. by extended period of time i mean 5+ days

when im outside I enjoy being outside and do not use my device except to check a notification or two. so when im inside and in an average lit room, I can drop the brightness to about 15% and that is enough for me. remember, lighting the screen is the phone's biggest battery hog. any decrease to this will increase your SoT. I enjoy getting an extra 2 hours out of my device before i have to be tied to a power cord
that said, im waiting for my zerolemon battery case to ship and can't wait

Fast draining battery after 1 week of use

I was very impressed with the battery life when I first got it. But now, after a week of use, I use to get around 24hr-35hrs of battery life from 100%. Now after checking the battery time, at 100%, it is reporting I will only get 12hrs now. What gives!??
I made sure that the apps that I do not want open on lock screen are closed.
The only new things I installed were games: Modern Combat 5 and Need for speed.
Should I calibrate the battery (let it drain and fully charge it up)?
Just wondering why now I am getting half the battery life that I use to get?
Mate 9 USA version
Build B138

Sell the phone.

Just ignore the timer and use your phone normally. Those timers are never accurate. When you hit 10% check the SOT. I'm getting around 8h with B138 for example but your mileage might vary.
Just enjoy your phone and avoid waking it every 5 min to check the battery stats. I find people do this all the time with a new phone so it rarely manages to doze.

Thanks for the tip. And yea, makes sense to not wake it every 5 mins, which I find myself doing just to check the battery level.
I'll see how it goes, but like I said, I was getting great battery life, almost 2 days worth of use, but now, just only half a day. Will see how long it really does last me,
Is there a history log of screen on time or average stats?

Be little clever and think that you didn't have this 2 games before lol

I've been having the same problem! First week was incredible - I could go 12+ hours and still have 50% battery left. Now it seems to have gone down by about 50%. I've installed a few more apps as time has passed but nothing crazy - I'm carefully monitoring app power usage now to see if anything's hogging the battery. Testing now and noticed CNN app was at the top in usage since my last charge and I haven't even used it in that time. Just set it to auto-close after screen lock. Let's see if that helps...

I'm on B138 update, i get about 16-24 hours of battery life, i do factory reset after any update, i only backup my gallery, then after setting up the phone and downloading my apps, i go to battery > close apps after screen lock, close all apps except the ones i need which are 5 apps
Before i did that, i was getting terrible battery life 10-16 hours
