[Q] G2 ate 45% of my battery in 1 hour (UPDATE)

UPDATE BELOW
So here I am sitting here on the verge of a fit that would not be good to have at work.
I went to my friends last night (a pro at android phones) and was hanging out with him. I brought up the fact that I have been having REAL BAD battery life. So he takes my phone and looks at it running some tests. He proceeds to look up at me and states " you better call t mobile and get them to send you another phone." *swears like a raving loony* This is after running the battery dead and leaving it on the charger for 8 hours to condition the battery. When he said that to me by the way he explained that my phone is searching for a signal 55% of the time and that is what may be eating up my power. NOW, I know for a FACT that I have a 100% signal all day long... I live next to a t moe cell tower and work next to one also.... and during my commute I have 100% signal.
I guess what I am asking here is has anyone else seen this happening on their phone? I also noticed after my buddy downloaded a system monitor that the CPU is running at 100% all the time. Common sense with computers tells me BAD BAD BAD.
Why am I so upset over this you ask? Well, the service of t moe's signal and quality of the network of where I live is GREAT! However I have had BAD luck with all the phones I have since I have been with t-moe. The Rzr: sent that back about 8 times ( went and got a windows phone with my own money after that), the BB 8900: 5 times, and now all this BS with the G2 after just having it a month is getting to be a friggen P.I.M.A.
I know they are going to want to send me just the guts of the phone and not a new one.... I WANT A BRAND NEW PHONE! I am sick of referbys. It's a waste of my time and money to be driving to the [email protected] mail box to drop off the return.
HELP!!!!!!
Your loyal 911 Dispatcher.
P.S. to give you a good idea of how bad the battery is being eaten up I was at 100% this morning at 6 am. Now I am at 64% and dropping fast. So I always have to have the phone plugged in.
Update people:
Yesterday when I got home I called T moe and talked to a Retention CS. I went right to the top. The lady I spoke with was either blowing sunshine up my arse or she was telling the truth so take it as you read it here I guess.
So first thing I did was explain to her (nicely btw) of all the issues I have had in the past with all my other phones I have owned with them. Of course she did sound concerned. I also went on to tell her that if we do go to the point of sending me a replacement that I wanted a new boxed phone and none of that crap in a UPS box with stuffing.
After some conversation and questioning of my phones history she advised me that:
1. The issues that I (and others) are having are known issues and they are well aware of it and are working closely (In bed with them?) with HTC about it and should be seeing an OTA soon with a fix. ( I will believe it when I see my phone).
2. I figured since I had her on the phone and laughing that I would press the issues of the teathering rumor... Now again take this with a grain of salt if you wish but the details she told me leads me to believe that she is very up to date on what is going on. She stated that in fact they are working on developing something about charging for teathering... I didn't press the outside apps for teathering though. She stated that it would not be a contract thing and that you could activate and deactivate it as needed on your account so that you were not always paying each month for it if your not using it.
3. Battery draining issues. Solution..... Sent me a new battery via next buisness day shipping. Said I had a bad battery.... Also told me not to keep the phone plugged in since that is the fastest way to kill your battery and that I should discharge it and rechage it as needed.
So there ya go people. Again take it how you want but I hope me spending this time typing this out helps. ( my boss is paying me to type to you guys )

Try pulling the battery off your phone for one min and then reinsert it into the phone. Was having drainage issues like you and that helped. If not try a factory reset. Who knows... that could help.

Try going to settings, applications, manage applications, and check and see which apps are tuning in the background. If an app is piling a load of data then that could be what is killing your battery.

Already done and done..... Only the basic componants of the phone are running and a few things I am always using handcent SMS, Beuty widgets.... and batt watcher.

Did you try a factory reset and not install ANY apps. Maybe that beauty widgets is killing your battery or batt watcher. Or you may have a defective battery.

my wife phone the 1st day battery ran out real quick but maybe because she was texting to much but i use my brightness at 100% and i wak up at 9 and lasts me to like 10-11pm and about 40min of uno played

Well my wifes phone is running the same widgets and programs that I am.... I take that back shes running 3 times the ammount I am..... and her bat lasts her all day and then some...

In the beginning my phone had the same problem too..but now its way better I use to recharge my phone twice a day but not nomore..I think just wait it out..that's what I did..and my friend also just bought this phone and she's having the same problem..I think its just when there brand new it does this

I ordered a evo / mytouch battery off amazon supposedly they fit the g2 and you get about 30% longer battery time.

just a quick update thread bump... update in my OP

I noticed this too. One day my batt lasts all day, and well into the next.
Other days (twice now) the battery, on the same setting, with the same usage,
drained obnoxiously fast!
This phone has some serious schizophrenic issues.

Battery Question:
Is the Tmobile G2 Battery 1300 mAh? ir 1400 mAh?
Only asking because I went through three G2 reviews and they all list it as 1300 mAh, however the HTC Desire Z coming here to Canada is listed as 1400 mAh... ?

Wait, how am I supposed to not keep it plugged in? I plug mine in before I go to bed and unplug it when I wake up. Am I supposed to wake up an hour and a half into every night's sleep to unplug my delicate phone? Why the hell don't they just have it stop charging the battery once it hits 100%?

I am 9 days in on my fourth G2 and until this morning i believed I had a keeper. By a pure twist of luck I did not have to get up at 5:30 am so as to arrive at the tennis courts to give lessons. Upon arising at 7:20 am I found that my battery had gone from 100% to 1% and turned itself off. The phone was in standby when I retired to bed and had not been used the entire night.. Obviously the alarm had not gone off and the phone was unusable. Upon plugging it into a charger it still would not boot up. After waiting 15 minutes and letting it charge I tried again and it did boot up and showed 60% of battery. I have never ever had a battery charge to 60% in just 15 minutes. Upon checking battery usage I found the following: Android system 27% Shop Savvy 23% voice calls 35% Display 11% phone idle 4%. I had not made a phone call and had not launched any apps. I certainly had not used Shop Savvy and the display had been off. I have noticed recently that upon waking the phone up I would be running various apps which I had not launched. I use my cell as my alarm so I cannot keep it if it is not dependable or is acting erratically. Has anyone else had this scenario happen? I have been reluctant to give up on this phone but after 4 units all with issues I guess its decision time. NOTE it just dropped 19 % in less than 3 minutes while in standby, with no apps being launched by me and the phone just sitting there in sleep mode. Just tried to access the market and no go. I am experiencing only G or E where I normally have good 3G or H. Perhaps this is T Mobile and not the phone but this happens way too much and does not occur with my Vibrant or Nexus One.

[Q] My New Desire :- Battery awful!!

Ive had my new HTC desire from 3 UK for a couple days now and although i had read the battery life wasnt great on these things im shocked how bad it is!
For the first couple days the battery was not lasting the day from a full charge in the morning so i decided to try the new leedroid 2.3a on it.
Still no better. The phone does seem smoother with leedroids ROM but from a full charge this morning 8AM to now 2:15PM the battery is already down to 30!! I have not really been messing around with the phone alot, couple of txt and a phone call but thats it.
Any tips on what i can look into to see whats killing my battery so fast?

Had same problem with sense roms untill i swapped to cyanogen mod. Running 6.1 with defrost kernel. Always have above 30% when i put it back on the charger, 15-20 hours. Used alot. Try a aosp rom. Guarantee better battery life.
Sent from my HTC Desire using XDA App

How much are you actually using the phone? I'd imagine you're on it quite a bit so of course battery will go down quicker
I also assume you didn't make a note of your original ROM version so you can go back to stock with an RUU if you decide you wanna send it back...

battery sucks...get used to it. sorry.
I've had a desire since may and i can count on one hand how many days my phone has lasted till bed time from a full charge in the morning.
some tips for you
3g kills your battery, 2g and sync on will use less battery than 3g and sync off.
get some power widgets to controll your phone, ie 2g/3g, sync, wifi, brightness, gps and use them wisely.
a bright screen on an amoled desire will kill your battery...turn it down unless you cant see it.
+1 for cyanogenmod

That is not true in all cases. My battery lasts more on 3G compared to Edge,not sure why. I experience frequent overheating as well when on Edge. 3G+WIFI Hotspot tend to last more than 2G+Sync.

I've been using auraxtsense for a while now, with browsing the internet, texting, maybe 20 mins of phonecalls my battery would last around 36 hours on a full charge, however i've gotten into the habbit of charging phones when i go to bed anyway.
I've left it for 3 days before doing nothing on it other than getting the occasional text message on some days off from work.

Battery Life!!!

if you are getting good, or bad battery life, take a screenshot and post it here and share your story!!!!
In the picture, im still at 72%!!!!! i know the phone hasnt been awake much, but still!!!

The phone hasnt been on almost at all lol

i wish my batter life was that good. i have terrible battery life. i get about 5-6 hours before i have to charge up again. i hope its just software related and not the phone

Its software related. Considering returning this and going to the dark side (iPhone)

If I never turned any of my phones on they would all look like this......I want to be able to use my phone and not have to worry about battery life.
Anyway, if you don't use your phone, then why do you even need it?

If you are going to start a battery thread and brag about how good it is, at least post a picture of you actually using the phone. No one really cares how long the phone will last if you do not use the thing......

If I didn't turn on my EVO it would look the same as well. Once I would turn it on though, that's when the game changed!
What I would like to see is people show their screen on time and how much battery they have left. That is the stat I am most interested in........I am thinking it is averaging about 3 hours of total screen on time...
I love the people that claim like 7 hours on screen time even with the EVO 3D. Do people really think this is believable with stock batteries that ship with the device.

Yeah, bad signal....might as well forget about that stat. lol
So if a GSM phone has bad signal, it won't be affected like a CDMA phone? If so, wonder why that is.

Here is the thread detailing the known battery glitch
There is no fix for the sprint version yet. Someone made a kernel for the international version that fixes it.
I returned my phone over this issue and I'm waiting for it to be patched before I can use it

Yesterday I kept my 4G radio on all day, sent texts, made a few calls, surfed the web, streamed Slacker and Spotify, checked FB and twitter, and hit 20% after 16 hours.

My stats for today.
Phone of charger for 13 hours and 47 minutes.
Screen on time - 3 hours 25 minutes.
Battery left - 9%
Used wi-fi, 4g, and 3g throughout the day. Screen brigtness set to 40%.

I'm getting a good solid 10-14 hours of use. I'll get 6-8 hrs if I'm pretty much using the phone nonstop.
Have you guys tried the battery calibration app from the market? A fellow xda member made it and it resets your battery scripts (needs root). I just did it this morning before I unplugged the phone since I flashed a new rom.
Battery life on this phone is so much better than the evo 4g. Stock battery life on this phone rivals my evo 4g with 3500mAh extended battery!

Go Comment or Star for Battery Fix

I'm sure we all know that the battery life on the G Nexus is pretty awful, so let's all go star and comment on the issue so we can get Google's attention!
http://code.google.com/p/android/is...s Owner Summary Stars&groupby=&sort=&id=22878
Just scroll all the way down to the bottom and star the issue or leave a comment too.

Done and done... I hope this comes before I need to return the VZ GNex

Hmm, compared to my EVO 4G, I barely had to do anything to this to get the battery life to be very good (estimate 100 -> 0 = 15hours). Maybe I use the screen less than you guys though.

At home, no LTE connection. 5.5 Hours.

On GSM.. battery life is stellar.. keep in mind, like the person who posted above me that if you are in a low signal area your battery will be destroyed searching for signal..

Yeah I don't have LTE where I am either, but I have it forced to CDMA only. Android OS is my battery killer. I usually get around 6 hours before having to plug it up.
I really think that if enough people starred the issue then it will get someones attention! (Crosses fingers)

Please star, but don't comment. There is enough useless comments there already, and everyone gets notified on new comments.

you probably have a rogue app killing your battery. if I let my nexus sit idle with LTE on I get close to 2 and a half days

Hi,
This high Android OS Keep awake time is not specifically about battery life issue.
We are discussing the fact that, because of this, the phone is constantly waking up (wake up state).
And that's should not happen while the device is turned off, for example.
Yes, of course, this will relate to battery life at the end. But, that's not the point of the discussion / bug as everybody has different preference of battery life. One can say 12 hours is enough, while others may say 24 hours is not enough, according their usage pattern.

Yeah I don't think that is the case... even after rebooting it stills is draining even when idle...

i aint charged in 3 days so im all good

This is nothing new. Android is a batt hog, plain and simple. You think google doesnt know this already. Its an "acceptable" item. Where they know about it & it's not the best, but thats what they get if they want a phone thats constantly using the network, has a large HD screen and is so damn good to look at you wont want to put it down.
Quit itchin and get on with it....

I have the extended battery from Verizon so keeping that in mind, my phone lasted 14 hours with 10% remaining with normal use. I stopped testing since I had to go to sleep
By the way I have Beweather and Facebook updating every hour and Pulse updating every 6 hours. I also have endgadget, Cnet, Google currents, Flickr and 500px updating.

So far battery life is a bit lower than I would like but not to a horrible state. definitely going to need the extended battery though. playing around today to see how fast I can kill it.
can't get photo to upload now though for some reason but got 2 hours 10 minutes with 12% remaining. would kinda like to see that as a stat added to phone reviews, minimum battery life. Max is fine but I'd rather know how long it will last with power using.

I'd say battery life was less than great on 4.0.1 but 4.0.2&.0.3 its pretty damn good now my idle usage is next to nothing. 2 days ago i had 47 minutes talk time, 1h38m screen on and about 13-15 hours of idle and still had almost 40% left at midnight.

I think you don't understand.
This is not about battery life, but the high Android OS Keep awake time. Which means your phone was awake when it's turned off.
Obviously, this doesn't happen on my HTC Desire, nor Nexus S with Gingerbread.

I can't speak for battery life on the LTE Nex as i have the HSPA+ version...I've found that the battery life is quite excellent after a few charge cycles...Have gotten 21hrs on a single charge with normal usage...if i'm watchin vids or playin games then im putting my phone on the charger cuz the screen really does eat up battery alot.

For those with battery issues.

Leave ICS and get back on GB.
Ive had this phone since the day it came out. Switched to ICS once the developers started dropping ICS leaks, etc.
For the past 2 weeks for some reason, Ive had nothing but HORRIBLE and i mean HORRIBLE battery life. Phone would not last me more than 4-5 hours of heavy use. I'd have to carry around my portable battery pack to charge the phone on the go. I did everything to my knowledge to try and conserve battery life. CPU tweaks, battery monitoring, tried different ROMs, Kernels, Modems, etc, etc. Nothing would significantly improve battery life. I even went ahead and ordered a new battery last week to remedy this problem (which has not yet been delivered/used)
2 Days ago I flashed back to Blazer 4.0 ROM (GB).
I unplugged my phone yesterday morning at exactly 7:30am. Did not step back into my house until 530 which at that point I was at 35% and had been using my phone all day as I normally would. Web browsing, tons of texts, Used Navigation for about 2 hours, etc. I did not plug my phone to the charger until 10pm. Phone was on 19% then. Mind you, this is on the first day of the Phone being on a new ROM/GB so the battery has not yet settled/calibrated as Its only been charged Once since flashing over.
I refuse to switch back to ICS for the sole reason that battery levels have obviously improved with something as simple as switching back to GB.
Just a heads up for anyone with ICS on their E4GT having issues with battery life.

If only I got a dollar for all the times a thread like this is made.. I'd be rich. Blah blah ICS sucks yes we know... So far my phone must be a super phone because it's handling ICS well.

I agree with you, Ray. I'd also be rich for every time I've read of E4GT owners who's phones are running ICS with no problems. But then theres the bunch who also complain that they have problems. I never stated ICS sucks. At this point these phones are old by today's standards. Be glad you're one of the ones who's running ICS with no issues. I for one will stay on GB until I switch to a new carrier/new hardware sometime soon.
Just thought I'd give some feedback of my experience with battery issues on ICS in comparison to then switching back to GB.

I don't know if you've tried Blazers ICS ROM, but that thing has some AMAZING battery life. I've been running it for a few weeks now, everyday I get at least 12 hours of moderate to heavy use, without my own tweaks, and by the time I connect to charger I'm at 35%

Arguments apart
i have a few friends all on this or that ICS and none of them is happy with the backup
whatever its a fact ICS goodness never really reached E4GT, lets hope FI03 onwards some sense prevails at those losers at sammy and they push something which we can smile about.
FYI i am also on ICS Rom , still in testing phase after getting my new white beast 10 days back , already tried like 3 , each for three days
running galaxy 1.8 since yday and hoping it shapes well otherwise i ll also move back to GB

I've tried multiple ICS rooms and I've always gotten great battery life (14+ hours with 3+ hours screen on time).
The only times I've ever had battery life issues were when a certain app was the culprit and was keeping my phone from deep sleep or causing frequent wakes, which is almost always the case with poor battery life issues.
Check out an app called GSAM Battery.. it will tell you what is using up your battery in easy to read graphs and percentages. Also, check out CPU Spy to see if your phone is actually going to deep sleep mode when you turn your screen off--again, it shows you in an easy to read chart with times in each state.

I got over 30 hours last weekend with light use, but the next day, my battery would drain 5 to 10 percent per hour with no use. I have all the utilities to track what's happening, but cannot find a definitive cause. Poor reception seems to be a factor, but not the whole story.
EDIT: I just installed GSam. Thanks for the tip!

Try the Re-Calked FI03 and tell me ICS sucks....this things is as good if not better than Calkulins v3 GB rom....the ONLY other rom i have ever liked.... :good:

Maybe you should've posted this after receiving and using your new battery. My phone had horrible battery life after a while on ICS but it turned out that it was in fact the battery and not ICS. Got a new battery and it is back to 18 hours a day (on ICS)

Only the stock ICS rom is garbage with poor battery life and stupid stuff like grey text on black back ground. I have ran several custom ROMs and they all provided better battery life. As I have said before, I got 99 problems but battery life ain't one of them. You must be doing it wrong.

Still waiting for the new battery to arrive. I would love to try it but I'm in the midst of a heavy usage of Verizon PRL on my phone. Sprint doesn't like heavy roaming users from what I've been reading. Sprint 3G in my neighborhood here in NYC sucks Donkey nuts. I can cross the street and get 3 bars more than I have sitting on my front porch. But thats a whole other topic of discussion.
Im not sure why my phone couldnt play well with ICS but it really was horrible. I consider myself a heavy user and ICS couldnt keep up with battery demands. I tried undervolting, etc. Oh well. Been eyeing the SGS3 or the upcoming SGNote 2. Time will tell.
So far 3 days on Blazer 4.0. All my apps are restored via TB and no issues with battery like I had on ICS. Don't really know what else to say. :good:

My phone would last a week on cupcake

I'm getting 24+ hours on standby time. I have gotten about 18 hours with about 3 hours of screen time. Facebook and GBA emus. I wasn't able to do this since GB. I have done this by doing one simple thing. Turning off data. I kid you not. Utilize that data toggle. I know at first you're thinking no I need data. But you don't. Unless you're some business person, then this excludes you. Wanna check Facebook?
Also, wii benefit from something else. 4G WiMax. You can turn that on even though your data is off. You still get decent battery life since 4GWiMx knows how to sleep. Also, if you're driving around, it'll pick up 4G eventually (unless you don't have it) and it'll download what it needs to download. So by time it turns loses signal, you'll have your emails. I tried this and I still got good battery life.
Using Battery Monitor Widget, I was able to see that my phone wasn't "sleeping". That's what the main problem was. That's why I wasn't able to find any rogue apps using Better Battery Stats. But I did see my phone stayed awake. Like once my phone died in 5 hours. 10 minutes screen time. 6 minutes of deep sleep. Really? That means my phone was awake for over 4 hours!? Doing what!? No app was at fault.
Extra stuff. No need to read if you felt you read enough
An app you all should check out...

Battery Monitor Widget (It's not just a widget. LoL!!)
It tells you how many #mA your phone is using. So if it shows 500mA. That means your phone is using 500mA per hour. Your phone has an 1800mA battery. So that means if your phone used a constant 500mA, it would die in 3.5 hours. This is a good way to see just how much power your apps are using, or if after 10 minutes your phone is actually sleeping. My phone actually started using 2mA. I haven't seen that since GB. I thought my phone would never sleep like that again. I cried.
P.S. If you get the app, in settings -> Calibration, change the battery amount from 1500mA to 1800mA. Apparently the app thinks our battery is 1500mA. Or maybe my battery REALLY IS 1500mA. I mean, it got my Nexus 7 battery correct. I didn't have to change it. I've always wondered why BMW said I had a 1500mA battery instead of 1800mA. I may have to look into. Wii all should probably look into that.
Also, those on Blazer ICS ROM. Using BMW, I was able to see something quite interesting. My phone would use a lot of energy. Like 1000mA just to send some text messages, or scroll through my app drawer. BUT, after I stopped using my phone for about 10 minutes, I'd turn it back on and BMW would show my phone gaining #mA, or charging. This means something is causing the phone to "drain", or show drainage, when there really isn't. The fact that the phone charges back means it never really used that much energy in the 1st place. But that only happens on this ROM. Since I figured out the data thing, I'm going to try CM9 again.
