Battery drains faster than it should - G1 General

Hello there,
I would really like some advice - my battery is draining like water. I'm quite convinced it is the regulation of the unit; I bought a 2400mAh battery replacement and it lasted ages on first go, but then my G1 started draining stupidly fast after I'd recharged it. This also happens on the stock battery too (buy even quicker!). I'm convinced it is the regulation because a) I've never had battery problems previously and b) the battery meter starts at about 26% when I plug it it in (after the phone shuts off from it being dead and I then plug in the charger).
I actually have a bricked G1 that still charges batteries, so I thought I'd do an overnight charge on the battery that way, to 'remind' the other G1 what a 100% battery is like, but that didn't seem to work either.
Can someone help? Is this a known problem? I would really appreciate any advice.

Things that cause ridiculous battery drain;
Backlight, keep it at no more than 30%
Wifi - turn off search for open networks,
Gps - wow does this drain

GPS doesn't really drain battery unless it's actively being used...at least not on my phone.
You can also try disabling 3G if you're not in a 3G area. It will keep trying to find a 3G signal, which really drains battery.
For the record, I have a stock battery that I get ~13-16 hours on from a single charge... my backlight is at 40%, GPS is always on, and I use wifi whenever I want to surf the web and am near an open network.
OP...if your battery is lasting you only a couple of hours, then I'd try to reflash your ROM. Might help...

Wow 13 to 16, I am lucky if I get 6 with 30% backlight, and wi-fi and gps off, I have always gotten that on ever rom even stock with no widgets, you are one of the very few with good battery life cause I have seen many complaints about short battery ranges

Yeah, that's on a normal, moderate usage day. If I use it heavily, with a lot of wifi and web browsing, then I'll get around 10.
Maybe your battery needs to be replaced... could just be old and not holding a charge properly.

It's 2 months old, has done it from day one, I also have another battery that does it too that I kept from a previously brick g1, so one 3 phones, all the same battery life but then I use it quite heavily, always browsing on the web since my computer burned out

try that? 3rd gen battery could help..

Thanks for the suggestions, but it's not a wifi/3g/brightness etc problem - I've had a G1 for six months, I know exactly how much power should be consumed. It's also not the battery; I have two stock batteries and a brand new 2400mAh battery, which for the first few charges lasted about 2 - 2.5 days and was brilliant (as it should be), but now doesn't last all that long.
I may have made the situation slightly better however - I did a Nandroid backup, wiped to factory (well, Cyanogen 4.0.4 anyway) and booted into that. I then restored the backup and when I plugged back in to the charger, the meter was at 85%, and seemed to take a normal amount of time to charge (and not jump to 100%). It remains to be seen if the problem is solved, I've yet to have the battery drain (this is a good sign though) an plug in the charger to see if it will jump from 0 to 25 or not.
I'll re-post when I know.

run the battery down until the phone shuts off without plugging it in.
charge the battery while the phone is off over night
do this 3-5 times and see if you get any improvement.
also remember some of the cheap 2400 batts from ebay and such claim 2400 but that is from 3.5V to 3.0V. The G1 considers 3.2V to be dead so you only get from 3.5V to 3.2V which sucks.

I'm with gridlock on this one. My batteries suck. It always needs a mid day charge. And to the poster that said to reflash a rom, that is bad advice. There is known issues with getting poor performance out of these batteries. I have 2 and both do the same. Got the second one from complaining to t-mo about how bad it sucks.

Reflashing seems to have worked...the 2400mAh battery seems a lot better now, it lasted nearly two days (it runs at 3.7v, according to my battery diagnostic), I've only just recharged it last night. When I plug it in, it charges normally and linearly now, instead of jumping straight to 25%.
So my advice, if anyone is having similar problems to me, would be to try a reflash.
Thanks for your help everyone.

X10 Power Usage

Hey.
Got my X10 a few days ago,
And im the only one with a power problem ?
Having to recharge it alest once a day ?
My batteri drops aprox 12 % per hour, so I usefully charge 2 times a day.
Since 1AM to now (12AM) it went from 100% - 24%. And Ive been sleeping alot, so the phone hasent been muched used either.
What kind of usage are you partaking in? In my experience most smartphones have to be charged daily.
Here's a post from Esato Forums where someone did an extensive battery drain usage test:
http://www.esato.com/board/printpost.php?post=2933402
The last day Ive been using it minimally, and Im on my second charge for the day. All my other phone last 1 day (6am-12pm) before needing charging. But my X10 needs an aditional charge at about 2-3pm..... And even then is as good as empty at 12pm....
I hope its just a small software bug, or something that could be fixed with a reset. Im starting to enjoy this phone, but there are several days a week, I will not have the time to charge it a second time..
Think Ill go for that reset, and see if that helps....
Anyone else with X10, and batteries that drain extremmely quick?
Mine dies after about 8 hours, but this is usually normal with new batteries, it should be better after a few FULL recharge cycles.

Were your previous phones smartphones, just out of curiosity.
Also, you could try to reduce how often TimeScape polls in the background for updates. That might help.
My current iPAQ 910c lasts a full day if I do nothing but the occassional phone call and SMS. However, if I do anything power intensive the battery fails, and the phone is done until it can get 2 hours or so of charge. But that's why I'm looking to replace it... definitely not normal.
I have access to every phone I want.. And Ive only been using smartphones.
(Currently as in sign.).
I dont use timescape or mediascape, so they have been disabled.
And yet the battery only last for aprox 10 hours....
I never had a phone with such a bad battery, however, Ive never had a phone with such big screen or cpu either....
You gain some, you loose some.
And to he who talked about recharging cycles to maximize battery,
this kind of batteries dosent work that way... They are allready maxed..
I've had mine for a few days now.
The battery's pretty good, I've only charged it once over about four days, so I'm pretty pleased. However, it does seem to use a lot of power if you have wifi on, even in sleep mode.
I've also had no problems with my "a" in either keyboard (Norwegian/Japanese) so far.
I'm still on 14 btw, if anyone's noticted battery dropping after they updated.

I would not say that the my battery is good. but it is ok, i haven't had it fully charged yet, since I did get git yesterday. and it did last about 10 hours or so, from 60 or 70%. with playing music, trying out some things etc. but I worked 5,5 of these hours and was in the movie theater 2 of the other hours.
anyways, I haven't really had much problems with the keyboard either, as you said. the only thing that really buggs me is the damn space button. it is too small! :/ I wen't from an X1 to the X10 no, from using HTC magic before that. But I am starting to get really used to the other keys.
I haven't installed the latest build/patch either.
//
Just download "spare apps" and see what apps som drain u battery
My X10 take only 6% on 3 hour on normal use
very very bad battery drain! Left mine on flight mode at 2AM with 50% battery left, before going to bed. Woke up at 11AM and the battery was dead with no usage nor cell connection!

A chellphone uses more battery when there is bad reception, because it tries to get a better reception.
Like if there is just edge, the phonei strying to get HSDPA connection instead, this drains more of the battery.
+ With android the phone leaves some of the apps running in the background.
I recommand that you get an app that can shut these down.
Like a task manager kinda..
eg.Advanced Task Manager
I hope this helps ye.
and if you go into "settings - about the phone - Battery usage" then you can see what apps that is draining the most of the battery etc.

As I wrote before, phone was in standby on flight mode: it means that NOTHING was running nor any 3G data was exchanged. I've had many Android phones (Magic, Hero, Milestone, Nexus, Legend) and in similar conditions they lost only a couple of percentage points of battery, not 50% like X10!! I do love this phone, but heavy battery drains is driving me crazy (and it's definitely not a faulty phone, since I know many many users with the same problem)

I actually think the battery is good too. I recharge every other day, which seems to work fine.
I have bluetooth and wifi off, and mostly doing manual updates for timescape. I do surf quite a bit though, and no problems with battery drain. In my experience, my X10 lasts a lot better than a Satio for example.
Strange how half of the people posting here, have very good batteries (1-2 days), and the other half have extremmely bad batteries (8-12 hours).
I doubt the ones with the bad batteries are "worse user" then the ones with the good batteries......
I'm one of those with lousy battery usage. Hardly use the phone, but drains in no time. However I've ordered 4 new batteries, so gonna test all of them and see if there's a pattern.
Grrr.. Was just setting up my contacts to Facebook.. Took around 20 minutes and drained 21% of my battery.. That's just not okay..
I just left it for 2 hours without doing anything and the battery from 90% dropped to 65%. This is not cool at all. SE we need a solution ASAP.
I'm one of those that get bad battery duration on the X10. I usually leave BT and WIFI on as I did in my N97. By observing who drains most of the battery, I get around 30% for the radio in standby and 20% for BT. The processor is only a small percentage (2%) so I don't belive that the snapdragon cpu can be blamed for bad battery duration. How is it possible that Nokias as the N97 having the same communication hw (GPS, WIFI, 3G, BT...) last for days with similar usage and battery capacity? Ok, the procesors are ony half the speed but I don't belive this makes so much difference...
I own a HTC Nexus also and has slightly better battery duration than the X10 but way far form the N97. I've roorted the phone and can change the CPU speed. It makes very little difference on battery duration if you set 400 or 300MHz instead of 1GHz.
So, it seems what makes all android devices so power hungry is the way the OS handles the communication interfaces, I belive most RF chipsets should have similar power drain and CPU's are idling most of the time. Perhaps symbian has a smarter algorithm to hanlde 3G/GSM/WiFi switching and no services polling the network when the phone is in your pocket.

So seeing i am in an area that does not have 3G I will have a problem with battery drain bcuz it will be constantly be trying to connect to HSDPA?

Interesting battery performance...

OK, I've had my HD2 since November, and I've never understood people who complained about poor battery life. I've consistently been able to go up to 2 days before charging. On the odd occasion, I've left TomTom running and it's drained the battery right down, but overall I've been pretty content with the battery performance.
Until about a week ago. I thought I'd maybe forgot to stick it on charge overnight the odd time, but now realise the battery has started to drain much more rapidly.
I did not change ROM, or install any additional software. I made sure nothing was running that shouldn't be in Task Manager. All of a sudden, I'm getting quite random battery drain - up to 20% drop in an hour. I put up with it for a week, thinking it just needed a hard-reset, so last night I decided to flash a new ROM. I updated to the latest radio ROM, and flashed bobsbbq's latest ROM thinking that would sort it, but after I took it off charge this morning it was down by 15% within an hour.
The drain has levelled off throughout the day, but it's still much higher than I'm used to. I don't use wireless, and I only have bluetooth turned on if I'm on AC power, so I've just got GSM/3G in normal use (and get good reception at home and work).
The fact that the battery drain changed so much in such a short period of time, with no obvious change in usage or software leads me to believe the battery itself is beginning to fail. I usually expect a good couple of years from a mobile battery before I see noticable drops in charge, but that's 6 months.
Is it possible the HD2 batteries are not very well made, resulting in some people having great battery life, and others complaining that it's crap?

I had read that some of the HD2 batterys were a bit dodgy as they were siphoning off the batterys from different manufacturers and as a result some are remarkably better than others.

I am precisely in the same boat. I am using my battery now for around 6 months. Since last week the battery seems to drain much faster than before. I am still analyzing what could be the reason, but I think it's the battery itself that is getting weak - far too early.

You said it yourself, the batterys performance gets worse for every day and should be replaced with a new one every 6 month, atleast.
Some feedbacks in other threads pointed out a possible and unforeseeable cause, the microsd card.
Try removing it and check battery drain, if that's the culprit try formatting it before throwing it away.
Also, as I stated in at least 3 other threads p) it's always a good idea to check battery drain with battclock, it should be 4mA during standby, any big variations from that mean something's draining while phone should be sleeping instead.

Battery life for the Nexus One

I've been hearing complaints about battery life with the N1. Fortunately I have'nt had that problem, but I did notice that my batteries don't fully charge even though the power indicator is green. I have two batteries, a standard and extended, and I checked the status in my settings and it said the battery was charged, but it only read as 94%. It would'nt charge past that while the phone was on. So, I turned the phone off and the indicator turned red, telling me the real state of the battery, so I let it charge in off mode until the battery light turned green, and it charged 100%. I notice with all rechargables when we first get the battery the first thing we do is throw it on the charger, when we should actually use the battery until it's dead, then give it a full charge. I did that with both my batteries, the one that came with the phone took about 5 or 6 hours to fully charge, and the extended one took a couple of hours. My battery indicator has about 5 bars in it, now I lose about one bar every hour, and my drainage never goes below 50%. And it's not like my phone is idle, because you know I have to show off my latest gadget, and I push android on everybody I know. So I let them browse the web, tweet, go on facebook, wifi tether, play games that support flash, take pictures, listen to music, explore the app market and play with all the apps we have, not to mention I'm making and recieving calls and checking my emails, and still my battery never goes below 50%. Idle I never go below 70%. Try my little method and see if it works for you

Thats how i usually charge my batteries too, and i dont get the same results. Maybe i need to shut off my phone.
Slow charging your battery also helps, too bad the battery doesnt charge that way. I use a third party dock/charger for HTC desire (Which uses same batt as N1) and it charges really really slow. The battery is cool throughout. And the battery life is astounding. Though not as long as yours. :\
Since i've had this latest Froyo update.. my battery has been GREAT. The best it's ever been by farrrrrr. When I manually updated the last time, my battery was horrible for a while.

What is this "extended" battery???
For me, I think the battery is average. It's not great,but it's not horrendous either. It's just that there's so much you can do with the phone, that you start using it more, hence the fast draining of battery.
At first I felt the battery was really bad, but when I come to think of it, I surf on the web, play games, etc. for like 5 hours each day. ( I know I'm a bad student.) This is with auto-sync, auto brightness, and my battery is almost dead around 5pm. It could be better, but oh well...
Froyo has greatly improved battery life to ridiculous levels.
Yes froyo has doubled my battery life by 5_6 hours
Extended battery

It came with my phone. I purchased my phone on ebay, and It was used, I got a dock and extended battery. I don't know if the dock came standard. I think it was a good deal though, I just visited the site where the guy bought the battery, and it cost $70 and I know the dock cost about $40. I won the bid @ $454, compared to the $580 I would have paid @ googles site. Check the link to see pricing.

Check out this post that includes instructions from an HTC rep for better battery life:
http://forum.xda-developers.com/showpost.php?p=6996422&postcount=100
I can confirm it works and so can others. It seems it is best to charge the phone when it is off.

[Q] Does battery get better after a day? If not, what can I do?

So I got my G2 yesterday at about 4:30. I LOVE it, absolutely (a bit of a weak hinge, and I had a random reboot and trouble starting WiFi at first, but it's seriously fantastic). But I'm having problems with the battery. At the store the guy turned it on and handed it to me, and I used it on the way home to the point that, by about 1.5 or 2 hours after turning it on the first time, it was at about 15% battery. So I started charging it, and then read an article online that it should be discharged, so I unplugged it after it went up about 4 or 5% in battery life to 16% and used it a bit more to drain it all the way. Then I read a different one saying you should never discharge it because it's Lithium Ion, and so I turned it off until I could get to the charger and then charged it and left it charging until I woke up at 6. Then I unplugged it, used it for about 20 minutes in the morning, and turned it off. I turned it back on at 3 today, used it mildly (Angry Birds, an emulator, and the camera, but couldn't get data access except very intermittent EDGE, no Wifi or GPS enabled) until 4:10, and noticed that it was at 65% battery life. The screen is on automatic brightness, and I have animations and a live background, but those are my only concessions. It said 45% of battery use was Android and that was the highest thing, I think display was only second or third (unlike my parents' Vibrants where it's like 66% display).
So that's 1.5 hours for a third of the battery, with moderate usage (I would argue that no data or GPS or wifi or internet usage at all is very moderate). So, on average, I could expect to get 4.5 hours of battery life? At one point it went from 55m unplugged to 1:07 unplugged and the battery went down about 10%. That's worse than my parents' Vibrants, and they say they didn't do anything to train their battery--and I've seen reports, especially on here, of people getting 10 or more hours of use with more usage than I had. I know you train Android and not the battery, but still, I have seen SUCH conflicting information on this that I don't even think it'd be helpful to search anymore (and trust me, I have). So does anyone know about this, definitively? Does the battery life get better after I charge it and discharge it for several days? Should I let it go down to a full discharge or keep it above 35-40%? Does it harm it to keep it plugged in after it finishes charging, or does it have a thing to stop charging the battery and just run off AC once it reaches 100%? Is it too late to train my battery now? Are there any official or reliable large-capacity ones for the G2, like a 1750 mAh?
Thanks,

Don't trust the battery meter. Fully charge your phone up, and it runs for forever. I've gone days where I unplugged it at 7:30 AM, and didn't plug it back in until 5:30 AM, and the battery was still above 20%. That was a day of fairly light usage, so that's not necessarily typical; with my normal usage (which is somewhat heavy), it's at about 30% by the time I plug it in at around 10:00 PM. The only time this isn't true is when I go for hours on an Angry Birds marathon :S
I have noticed on all my android phones that the first couple charges seem to drop much faster and each subsequent charge seems to get better. I run mine all day with push work email and vibrate all day and am upset when it is below 65% at 10PM and I unplug it at 7:30 am each day.
But did you guys do the same thing I did (15% then charge overnight) and then get around the same life, on your first day? Is it likely my short charge the first time did any damage? And are there any apps to provide a more accurate battery meter, preferably in place of the stock one?
Thanks,
Rocky
I did nothing special. I put it on charge when I got it but did not do a full charge before leaving work and going home. Did a full charge that night.
I plug it in each night when I go to bed and it has been as high at 70% and as low as 30% depending on how much phone and data time I spent that day.
I unplugged mine today at 7:36am and at 4:06PM it is at 79%.
I use battery indicator from the market. It does not poll and only listens for the OS battery change broadcast so it does not use up battery by running. Some poll and as such use battery to report.
The general thing about Lithium Batteries is that a full discharge is bad if the voltage level goes below a certain point to where the onboard circuits will disable that battery permanently. Most of the time the boards only do that if it's left discharged for a long time I believe, correct me if I'm wrong here.
Ideally, you're not supposed to turn on the phone when you got it. You were supposed to charge it till green and then you could use it, but I'm pretty sure not everyone can resist the temptation to turn on such an awesome phone . The battery life will blow the first week of use. I don't know why, but it just does; you'd have to break in that battery. Then the general rule I follow is to perform a full discharge once a month and then do a full recharge.
I also placed my phone on GSM AUTO PRL but for doing that I just exchanged some low 3G signal threshold for Edge; the extra battery life I got though is just that much more useful to me. Using WCDMA Preferred, the phone just wasted so much
To answer your questions, my experiences with the N1, Vibrant, and G2... battery life just blows in the beginning but gets better with use. The first charge you did shouldn't have damaged the battery but I think you may have wasted 2 of the possible 400-500 cycles that battery is capable of doing what you did. Finally, I use BatteryTime by Motalen for the status bar battery indicator which shows the % left.
Yeah, it just sucks because the guy at the store literally put my SIM card in and then turned it on and handed it to me. I probably wouldn't have turned it on until it had charged if he hadn't, or at least I like to think so.
So it's good to do the discharge thing once a month, and probably not bad for the battery to let it dip down as long as I don't prolong it too much? And I'm okay to just charge it and use it during the day, basically, from now on?
Does battstat poll the battery or just listen?

Nonsense. The battery runs down fast the first week because you got a new toy and you can't help playing with it all the time. After a while the novelty wears off and you use it a lot less. The battery doesnt just magically get better

See but if that's true then I can only expect 4.5-5 hours of battery life which is not what the G2's supposed to get. Which means either I DID mess up my battery instead of just running through some cycles, or I have a bad one, but not horribly bad, just for some reason only like 60% as good as everyone else's. I do agree about the novelty thing (it's my first smartphone), but understand I was not really doing all that much when I drained my battery like I said. Not nearly as much as it should take.

Those damn birds aren't content to kill pigs; they have to go after our batteries too!

I'm hoping that's the case. I remember receiving my N1 and I got to relive my childhood days for 12 straight hours. Regardless it's pretty sad to say that I leave my G2 at home while at work and it's down from 100% to ~60% with Wifi on (and with it staying on in the advanced settings) and GSM Auto PRL; I work a 8 hours shift. I left my N1 at home to mess with my G2 at work and my N1 went from 100% to ~80%.
Those 100 extra milliamphrs shouldn't do that much of a difference. Not to mention the N1 is slower and on a 65nm process. Did I also mention that both my G2 and N1 run the same services and 3G is also disabled on my G2 since I don't have my new SIM activated yet? Also, Latitude is always on for my N1.
It's just my experience though. I'll give this a good thorough test when I get the time. That or pony up for an extended battery.
On the other hand, my wife's GalaS is doing just fine in terms of battery life. Matching my N1 with the same settings and services.

X10 battery drain solved - by buying a new battery

So I always assumed the battery drain was a hardware or software issue, especially as my X10 would often shut down on 40% power and refuse to stay turned on unless the battery were taken out for 5 minutes.
Rather than buy a new phone I thought I'd try a new battery (I have had the phone since August 2010) - just £3 from ebay, and since then my battery life has been astounding - I'm quite a heavy user, but would almost run out after 8-9 hours despite keeping everything off and only switching on 3g and wifi when necessary. Now I can leave wifi and 3g on all day, leave the phone at medium brightness setting and still have 40% after a 15 hour day of medium-heavy usage.
I used to get idle drain of 1% every 10-15 mins as well (unless the phone was rebooted), but that seems to have disappeared as well.
So before you give up on it, do try a new battery, especially if you've had yours over a year. If there's no effect, you've lost £3 and still have a spare on hand.
Hello friend,could you please post the link where did you buy?
You think people on here throw their phone away because of battery drain,and it doesnt cross their minds to buy a new battery.....instead of buying a new phone.
I just hope your £3 battery doesnt damage your phone........or explode when youve got the phone in your pocket.......or during a call

Whats the size? i have a 1500mAh and a 2600mAh whats ur cpu settings also? looking for a good setup thanks in advance!
Also amazon link for 2600mAh btw its a big battery, and requires its own case which is rather bulky (http://www.amazon.co.uk/Sony-Ericss...TIMS/ref=sr_1_1?ie=UTF8&qid=1331594837&sr=8-1)
This is the 1500 i currently use, still getting the battery sorted with kernels ect
(http://www.amazon.co.uk/KC-Electron...1?s=electronics&ie=UTF8&qid=1331594882&sr=1-1)
I would just like to confirm what OP wrote. Not only did my new battery (I got the 1800mah one from Mugen, $33) solve my battery drain, it also solved my mysterious reboots, lockups, and heat issues. My phone would regularly get up to 48 celcius, it would result in it automatically shutting off the charging. It was a pain in the butt when using GPS on long trips as I would have to have the AC run straight onto the phone just so it would still charge. It was like this from new. With the new battery it has not budged above 29 celcius with GPS navigation, 100% screen, bluetooth, music and sync all running at the same time, I am shocked!
In order to condition the battery I turned off the screen timeout ("No screen off" in the Market) so I could get it to drain to 5%, it lasts twice as long even with the screen on all the time then it did before I got the battery, feels like a new phone.
beware of cheap batteries
beware of counterfeit batteries. Ive read a bit about cheap batteries being inferior knock offs. You tube has several vids about how to tell the difference
I'm about to buy bigger battery for my x10i. Now I have original 1500 mAh. Do you, who already tested thease 2500 mAh bateries see the difference?

My phone starting doing the exact same thing... shutting down at around 40% so I order the Mugen 1800mAH battery as well. Should get it in a few weeks... I did see much cheaper batteries available but figured you get what you pay for, and the reviews on the Mugen batteries seem to be good so I spend the extra money for it. Looking forward to the extended battery life!
