[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.

Then I would call tmobile...in your best interest.

Yeah I will sooner or later.... I just dont want to deal with it right now since I spent a total combined time of 4.5 hours on the phone fighting with them about my order for the G2.... I don't know how much longer I can be nice on the phone

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.
Sent from my HTC Vision G2

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.

Amen!!!!!!!!!!!!!!!!!!

Got an extended battery...

...and its wicked (IMO..I've heard others not have good luck with them..)
Basically, I've gotten 22 hours of fairly heavy use.. web surfing, Facebook, gaming (order and chaos mostly) among other things....using auto-brightness.
Now that I have another battery...I'm going to unlock/root and get to work flashing like I did on my DX.
A question though.. If I use my extended battery exclusively, and keep my standard battery as backup... Will my standard slowly discharge over time not being plugged in? Idk much about batteries..
Thanks so much,

It will yes, expect it to loose approx 30% over a period of a year being idle. Nothing to worry about.

Oh okay. So popping it in once a month should keep it up then?
I just want to be sure I have one handy because I once got into a corner with my DX where I needed a full battery to .sbf and mine was half dead and wouldn't work...so I had to hunt a friend who also had a DX down to fix it lol. Just want to be sure I don't run into the same problem >.>

It will lose very little capacity not being used. He meant it will lose charge just sitting there. Just don't let it sit empty. Or at full charge.

You should be fine, lithium-ion batteries hold their charge pretty well. I've not actually tested them before, but try charging it to full and then booting up to see the charge in 28 days later, might be interesting to see.
I know my Nikon D7000 batteries hold their charge very well, I tend to leave one in the camera and discharge the one in the battery grip first and just use the battery for a month or so and swap them around. In the same sort of time, 28 days I can lose up to six percent this time of year, but I am going out everyday in temperatures as low as -12°C, so it's to be expected.

For this Id like to know some additional information... what widgets you have running. Stock or ROM and what kernel. As well as settings like display, sync timing etc.

If you want to store your LiIon battery it's best for the battery to have ~40% charge. The battery will age the slowest this way.
Do not store it at 100% or 0%. Check every 6 months and recharge to ~40% if necessary.

This also reinforces what I've heard. Store these type of batteries around 1/2 charge never full never empty.

Horrible battery life while just being idle?!!?

I've had this phone for about a month. Started off on stock, and rooted it and flashed different ROMs and kernels. I never really got good battery life with any ROM. Typically I would get around 7 to 10 hours of moderate usage.
I fully went back to stock firmware and kernel using ODIN, to flash 2.3.6. I rooted it and removed some bloatware apps. BUT, the battery life seems so bad.. it's been 2 days, I've done calibration 2 or 3 times.
Leaving my phone idle, in one spot, I lose about 4-5% an hour. 4G Data on, wifi off, 2/4 bars of signal, sync on (only gmail, google docs, contacts, calendar).
But today, I think it got worse, as shown here: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230121.png
Graph: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230126.png
Note: the data icon on top shows that it's on 3G, because I moved out of good signal area when I took the screenshots. The phone was idle in a spot with 4G getting 3-5mbps.
What's wrong with this? The phone is a month old, so I don't think it's a battery problem. I've calibrated 2-3 times since I went back to stock.
Also, don't recommend me to use Juice Defender. I use Google Voice to call and text, so I need data on all the time. And I know this phone can last over a day with data on (my friend has the same phone and it has lasted 2 days on one charge, completely stock firmware).
ALSO, when I press "Android System" on the battery history, here's a list of what it shows:

Actually that would be more of light/medium. Checking facebook every 30mins, a few texts now and then, playing a game for 30 minutes, listening to music for an hour, a call or two about 2mins each, a few instant messages on facebook, GPS use for 5 minutes, and idle for about 5 hours. Brightness at 50% or below. All on data connection, no wifi.

I see easily over 12 hours on a charge with my phone, and i use it heavily... 2 to 3 hours of phone time (at the least) wifi tether here and then, a lot of facebook iming and checking. Reading....
Something i noticed though. I got the phone in October or so, and the battery life started off pretty bad. I didnt do anything special, i figured it would be bad with such a massive screen. Over time though the battery improved, and now im seeing wonderful battery life. I usually unplug it at about 6:30 or so in the morning when i head to work, and yesterday at 10-something is when it started *****ing it had low battery life.
Moral of the story? Be patient, itll get better as time goes by.

Your battery looks fine. Playing games rapes the battery. Also 4g rapes the battery.
There are ways to improve the battery but like you said... You need to use all of these features.
Go get a spare oem battery or a reputable extended battery.

Im at 52% right now, 34% display, time on 3 hours 14 minutes, and sitting at 1d 1h 39m on battery. Light usage.

Something is definitely draining your battery. As you can see your phone is awake when the screen isn't even on. It's just likely an app you downloaded or something in the background. good luck narrowing it down

Just right now i'm on a bus and lost 5% in less than 10 minutes. Listening to music. All i did was send five texts, check Facebook for a minute and read the posts on this thread. That doesn't seem normal at all. 4G on, sync on.

2050mAh wouldn't get you to much more out of thr battery..
Only 200mAh over stock, hows this supposed to help if you have a sleep mode issue or app issue?
Bringz me back to my first statement.
Your kernel is NOT allowing deep sleep mode for whatever reason, your best bet would be make a backup
Delete data/factory reset and try it over a day.. if it works good, its an app issue, still the same. It is undoubtedly the kernel. Why pay more for maybe an hour out of your phone?
Run some actual tests to clarify the issue first..
There. I said my peace

If you tried everything else try recalibrating the battery.
I have seen this happen most often when flashing new ROMs. Especially if you did not wipe your system, data, and caches before install it seems to encourage this.
To Recalibrate Battery (must have custom recovery like cwm):
Charge phone to FULL
(I highly recommend AC charger for this)
Reboot into recovery
Look for wipe battery stats (should be I'm advanced if not main menu)
Unplug phone and restart it
Now FULLY KILL THE BATTERY
(for faster results set mp3 or video on repeat and let her rip)
Fully charge one more time and done
(again I highly suggest AC adaptor)
Keep in mind if you set your CPU to Max frequency or leave a demanding app running and CPU is set to allow full usage ondemand or performance the phone will kill battery very quickly.
Same if you leave antenna on auto 4G and it is weak around you and phone is always searching it will go fast as well.

You sir, are a n00b, calibrating the battery is useless to this device and actually done automaticly.
So your post is useless and rather a waste of everyones time even reading. So thanks.
@above
Its obviously not hitting deep sleep, there's no way it can be and be draining the battery this quick.
@OP
As suggested above use cpuspy to check on the cpu when idle,
Sleep mode should kick in within 30sec to a minute.
Also chek my reply a few posts up and follow steps there..
Ignore Realn00b's post
Again:
@Realn00b
Please take the time to read up on batterystats.bin and find out what its for,
You don't need cwm to delete, just root explorer.. its in:
Data/system/batterystats.bin
Also, the entire basis of this is stupidity and was takin way out of context.
Batterystats is used to cache the active information of running applications (uptime/cpu usage, etc. NOT battery percents)
And should only be deleted under very very rare occasions (effecting above)
Your battery percent, is actually the mAh
Your system collects the information from a chip on the battery, among the information read, max mAh and current mAh.
The device then calculates from these the value we know as the percent.
Meaning, no device with a lithium ion battery stores charge information for the battery, making the entire purpose of your post for this, or ANY device not only useless, but also a little pathetic considering you would actually try to post a tip on something you are obviously completely uneducated about.
Please don't provide tips unless you are 100% sure of the situation and are actually educated on the material. Thanks

I originally purchased it for two reasons:
1. For long trips or for when I'll be gaming a lot
2. It had no reviews, so I figured I should buy it and test it. It's cheap anyways, $11.
Also, I'm on stock kernel. Everything stock + rooted.
I just did a re-flash with ODIN, so it has all the bloatware back on. I rooted and installed most of the main apps I use (facebook, aim, xda, google apps, games, basic things).
Currently I have sync on for Google contacts, calendar, and gmail. Facebook syncs with existing google contacts. T-Mobile contact sync off. Dropbox auto uploads camera photos on wifi only (I rarely take photos).
It's charging right now, at 50%. I might not have time to leave it idle today, so I could try in the morning if I have time.

Yea your right that is a good price.. is it same size as stock and have NFC? can you post link?
Thanks.
And please excuse realn00b up there..
He didn't know wat he was talking about.. read my post below it if you want an explanation.
Take a look at the safe to remove apps list aswell I'll see if I can find it on google pages for you. I definitely recommend
Deleting unndeeded applications and even replace stock with third party where applicable.

Battery reviews

I know the HTC One has been around a while on other carriers. Has anyone seen any reviews on how long the battery lasts?

I saw decent battery life in other reviews. One thing that caught my eye as a negative was that it had very slow charging times compared to other phones.

The slow charging time was in an early 4.1.2 build. It has been fixed though already in a previous update.

I read they turned off the fast charge mode for it, I think in an effort to make the battery lifespan last longer.

I read that it slowly charges the battery on purpose. It allows the battery to last longer since it's not removable. Apparently the fast charge fries batteries pretty quick.

Fast charging a battery phone is not really going to fry it... but there is truth that if you slow charge a battery, it will last longer.

I had the HTC One on T-Mobile for a while before switching back to Verizon and it got through the day with moderate to heavy usage. Overall you should be able to get a day out of it at least

What do you have now? Would you recommend the HTC one?

Power Saver
Did Verizon remove Power Saver from their model? I can't find a setting anywhere. I know that 4.2.2 removed it from the notification screen, but it's not under the battery settings either. Anybody know?

I'm back to the HTC One. The only reason I gave it up was T-Mobile coverage was terrible in my area

OK...My first full charge from 100%...the results???
I'm at 6% after 7 hrs 53 Mins
After a full days work (8 hrs) w/ my S4, I usually have about 65% left...I am hoping it will get better!

What was your screen on time? The only other reason I can think of that contributed to this was all the setting up, syncing, and downloading that you may have been doing on this first full charge (unless you did that all of that prior to this full charge)
Edit: Nonetheless, thanks for sharing. Hopefully it is indeed going to be much better than that on a regular basis.

It'll be a few weeks before I can tell if the phone's batter is any good. I'm spending a lot of time on it.

Yea they did, there is a Qualcomm snapdragon specific power saver app in the play store that is supposed to be a viable replacement.
https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app

All I know is that in the first few days to a week of me having a new phone, I get horrible, HORRIBLE battery life. Why? Because it's shiny, it's new, it's interesting!
Give it a few days to a week and you will be back to mostly normal usage. I know that after the initial new phone excitement goes away, my battery life usually doubles.
Not to mention the battery cycle break in. I'm not sure if it's real or not, some people say it is, some say it isn't, but apparently it takes a few charge and discharge cycles for your battery to get to a normal state?

I read somewhere (pretty sure anandtech) that with these new batteries, it is advised against fully discharging. The optimal state is to charge it when it hits 75% ish.
If a battery dies, it dies, but you should not be purposefully killing it. I'll try to find the article, but I'm busy at work right now.

I don't know where you heard that, but for Lithium Ion batteries, over-discharging happens when you are around 2V or less... most phones will turn off when the battery gets to around 3.2V
Fully charged is roughly 4.2V
Most of these batteries are good for 250 to 400 charge cycles, It doesn't matter whether you are at 1% or 80%, the phone will stop charging once it gets to 100% since you cant trickle-charge Li-Ion batteries

From what I've heard the battery is good for a day at best.
I've been debating One vs. Maxx for a few days... so confused... Battery Life vs. Sexy!

Just got my HTC One from Verizon. I am coming from a Note 2 which got excellent battery life but the phone was huge. The battery life is actually decent. I had the DROID dna and the battery life on that was horrible. So far it's pretty decent.

[Q] Battery calibration anyone succeded?

Battery calibration anyone succeded?
Hi I have a battery calibration problem on my GT-N5110 Note 8.0 that I bought refurbished through amazon. I know it is the calibration since the battery usually drains pretty fast and when it gets to 1% it stays there for around half to one hour of continuous use. Also sometimes when I'm charging it, it jumps from around 60% to 100% and "charged" shows up right after that happens, when I unplug it and use it, then it goes down normally (fast) 1% at a time, even though that big jump while charging happened.
I have tried several "full cycles" without success and haven't been able to find a real way to calibrate the battery meter, neither here or on google, and since I didn't buy it in my country, local samsung support say they can not help me.
I'm on 4.2.2 leak rooted and the drain has been present since I was on 4.1.2 stock.
If someone can get a hold of how to calibrate, it would be really nice if you could share it! Thank you!

I tried the battery calibration app before, and really didn't do a thing for me...

I also suffer this weird battery behaviour with the device charging, it will take ages up to about 60%, and then instantly its at 100%
I also get this on the way down... when im using it, the battery drains fast, but when I get to 35 -40%, I then suddenly get the low battery 15% warning flash up, and then im all out of juice.
This is the same whether im on 4.1.2 or 4.2.2 custom or stock firmware
I rarely get more than an hour screen on time, and thats with fairly low brightness and power saving mode on

If someone could some how contact Samsung and ask them about the real calibration it would be very helpful for us having this issue... Since some don't live in the US and don't get the correct support :what:

I don't have the same issue,so I couldn't help. Sorry.

I need help with this too!
Battery decreases so quickly when wifi is on! hardly get a days use out of it...:crying:

One method described in the battery performance thread which I've found effective:
"I wanna share my trial of battery calibration that really make a significant different at least till now .. I used to make calibration by discharge / charge cycles, but this time i add an official instruction of Apple:
- discharge the battery by ur normal usage till 1% then let the device play an HD movie till it shut down (that may take some time as it for me takes 4 hours!!) then turn it on to make sure the battery read 0% (my previous calibration the battery always shut down at 1% and I never see that 0% as I was discharging it vigorously) after making sure it is 0% it will turn off by itself anyway.
- now leave ur device turned off for extended time (about 5 hours or more is better according to apple "u could let it while u r sleeping"
- after that turn the device on and plug it in as it is on
- left it charges as it likes (for my trial it takes 7 hours and didn't say charged!! but I had to unplug it as I had to leave the work!)
till now my battery is really significantly improved, hoping to continue like that and I will keep u updated
Hope that helps :good:"
Discharging it completely, leaving it dead overnight then giving it a full charge by plugging in as a soon as it powers on has yielded good results for me. However I've also discovered a severe battery drain bug in stock Kitkat which has nothing to do with battery calibration; using wifi on certain routers causes Android OS wakelock which persists in deep sleep. I use my old Galaxy W as a hotspot for my Note 8 and consistently my battery drains overnight in deep sleep with wifi on. At my workplace we have a Linksys E2500 router, I leave the tablet on wifi throughout the day and don't notice the Android OS wakelock. So if you're having inexplicable battery drain test your Note 8 on different routers.

Calibration is a myth... google stated calibration tools do not help with how Android functions with battery management.
I posted my thread about battery and charging cables, and replied an a few topics like this one, yet nobody will search on Samsung DVFS disable or take note of it as being the cause.
Root with saferoot if you have not rooted, install xposed framework if not done so, and Wanam Xposed or Wanam DVFS disable. Since over 10 months now, my battery stats and performance are trouble free.

I was having severe battery drain for a while until I tried something I read about. What you do is carefully open the note up and disconnect the battery for about 15 minutes (they recommend a longer time but I don't see the need). Connect it back up and put the note back together.
It worked for me.
Google it, there's even a video on how to do it.

I was down to 3 hours or so of battery time but bought a replacement battery from a company called New Power 99. Cost $65-ish US and now I can go all day and still have at least 25% when I hit the sack at night. Huge improvement for me! I"m not a heavy user but I take notes at work, do some surfing, then read and surf alot at home at night. So far it's been great! Might think of a replacement battery. Probably cheaper one's out there but I wanted to get what I paid for so shelled out the extra.

Hi! Thanks for the info! That's great to hear, one question, did you change the battery yourself? If so, could you provide a hint on which guide you used, that would be verry helpful:good:

The battery came with a DVD that explained it (with really bad music) but the bottom line is you pry the back off, take the 8 screws off, unplug the old - plug in the new and replace everything. Not really hard but, as I said, nerve-wracking! I was afraid I'd screw it up but it was pretty straight forward.

That's awesome I would like to buy the same one in case something goes weird and need instructions to follow. Do you remember anything about the seller/model/site you got?

Yeah, just go to Amazon and search for "new power 99 battery replacement kit". Then pick Note 8 from the list. eBay has them too.

Will do! Thank you very much! [emoji4] [emoji106]

Any time. Hope this works for you. It did for me.

I. Had the same issues, I just took off the back cover and disconnected the cable that connected the battery. I did not need a new battery. The toughest part for me was disconnecting the battery cable... I actually had to take out the 8 screws that held the battery in place, so I could get some leverage. I only had my battery disconnected for only 5 minutes and it solved the problem for me..... Good luck!
