Is the battery meter accurate on any builds? - G1 General

Im going nuts. Literally none of the builds ive used have had an accurate battery reading. Ill go from 100% to 30% in a couple of hours with zero usage, then turn it off, plug it in and it will be in the 90's. Or ill turn it off plug it in and will go up by 10%, 20% or some other random number. Then sometimes ill go from 100% to 50+% in a matter of hours with zero usage and it will stay like that, it will just drain from there. And no i dont have gps or wifi on and the brightness is default and i just got a new g1 in the last couple of weeks but no improvement... This has happened with EVERY build i can remember trying (at least 25 builds total since rooting) except maybe CCyrowski's mytouch which im about to flash as my last hope
At this point, ill use any build with an accurate battery reading, even one with a horrible theme, any suggestions? pleas? thanks
builds ive tried:
ion
ion2
most hero builds
various builds by:
thedude
cyanogen
haykuro
cc
great builds but ive had it with not knowing how much battery i have left

Have you calibrated your battery recently, ie let it die completely so it shuts off the phone, then charge it all the way to 100%?

yeah i actually did try that a couple of times, but no luck. I though maybe my battery was going bad so i stole my wifes battery a while back but no better. If it wasnt SO off I could live with it but it seems like its gotten worse and worse over time

try a battery widget theryre usually more accurate than the normal batery indicator

thats happens to me sometimes, I think its just the battery itself.I left my phone on with nothing running at 20% came back one hour later and it was DEAD.
while other times I'll be at 1-2% listening to music trying to drain it and the damn thing will keep going for hours

Why would a bettery widget use different information than android itelf? Wouldn't it just pull the battery level from the system?...

Battery life sucks?!

So last night was NYE. I took my phone out with me and the battery was at 100% according to Touch IT ROM.
I took 4 or 5 pictures which were terrible, the camera sucks.
I stayed at a mates and woke up this morning, the battery was down to 20%?!
I haven't even used the phone and after 16hours or so the battery was nearly dead. What the hell, am I doing something wrong.
I always thought the battery sucked but this is a joke

same here ill try to get a new one
Check if you have any applications running in the background. Do you have Wifi turned on, bluetooth? Every module that is enabled keeps sucking power. If you don't turn them off, your phone can indeed get drained pretty quick. The battery is just fine, 1500mAh isn't bad at all. Do keep in mind that - due to the big screen and many options - phones like this just don't last for a week.
Also, did you fully uncharge your battery when you first used the phone?
If the problem persists, you can always contact SE to get a new one, as it's not supposed to drain that fast.
I know on the old P990 if you didn't exit the camera app correctly it just ran in the background and drained the battery. I do a double check in the task manager every so often to ensure that nothing was left running that shouldn't be.

I am testing this now on my X1 because I am alos not happy with MY battery life.

the camera is not that bad, actually it's one of the bests I seen in a mobile device... anyways, don't expect to take, for example, good night photos, but actually, with good lighting the photos came really nice.
as for battery; I'm sure you shoudl have something (maybe wayfinder) running in the background, with moderate use I get 3-4 days of battery without problems; and I never let it get down 40%.
i get about 2 days max on my battery. thats with nothing running in the background, althought it does ckeck my emails every 15 mins.
shame u cant buy a bigger battery like a 3000 that would last twice as long as 4 days on one charge would be amazing
Hm.... i have another one for you guys. I was using the phone non stop for the past couple of days. Wi-fi is always on and i watch media and use opera a lot. The battery lasts for about 8 hours. When i got the phone the battery was almost dead. I did charge it but for a couple of hours only. Then i charged it overnight for 12 hours. Did the fact that i did not charge it for a long time from the box affects my battery life???

yeah, i did that with a phone i bought about 2 years ago and had to get a new battery as the original one would die after a day or 2 (should last about a week as was standard phone). i always leave a new phone on charge overnight now so i know its charged all the cells
I'm not going to say that you guys are wrong, but...
This phone, does not need to be fully drained the first time you use it, nor does it need to be fully charged. That was only an issue on older batteries, it's not an issue anymore.
I also believe it says so in the manual somewhere So, I'm guessing you guys had some defect batteries, cuz it's not an issue with the battery thats in the X1.
are you using Itjes latest HD based rom?
I found I got really bad battery life out of it for a couple of days till I let it run down to under 10% then charged it again. It's working fine now.

I heard the same thing from a couple of people. Older batteries had that problem but modern ones don't. I just wanted to make sure =P
u might be right. like i said it was about 2 years ago it happened to my phone. but why take the risk
The only thing I had on was wifi and check mail every 30minutes.
I only use general useage (8 pictures and a few messages)
but that was it. I dont understand. I charged it for 20mins and its gone from 20% to 60%.
7hours later its only on 50%. Strange thing is, my phone has been on a radiator all day and it hasnt last that much charge.
Last night it was freezing -4c outside and wasnt that warm inside, then I slept in a cold room. I wonder if heat has anything to do with it :S

Did you flash your phone recently? was the battery at full before you flashed it? it's been reported as a problem on other phones (I remember the UNI used to do this) that if you flashed when the battery wasn't at full it messed up the power levels.

Just a sidetrack with regards to batteries...
When I charge my X1 with the device turned on, the battery tends to heat up till even the casing is hot to the touch. Is anyone else encountering the same thing?
However, when the device is off while charging, the battery doesn't heat up.
Weird...
It depends on what applications you've installed.... Touch flo drains it like hell.
My phone looks like this.
I use SE panel 1, no other gimmicks.
Pocket player for music 2 hrs each day.
15 min of video here and there.
2 hrs of phone calls, and a hell a lot of messages, which means keeping on switching the phone from potrait to landscape and so on...
SPB phone suite.
SPB wallet.
SPB Wireless manager.
I get a solid 2 days with about 15% remaining at the end of the second day...

As much as possible put the phone in sleep mode when you charge the battery. And the battery gets more heated up when charging over USB.
Hi!
I had the same problem some days ago. Even if the X1 slept on my desk with no application running, after 2 days the battery was empty.
I thought about what I installed last and deinstalled Batti. And now the battery lives much longer.
Btw... does anyone know a good app to show the status of the battery? Or how I can show it instead of the clock?
Batti was great but charging every second day was not.

Horrible Battery Life after Installing Android! :(

After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

You can look at this thread
http://forum.xda-developers.com/showthread.php?t=770903
It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .

Unlimited battery? Glitch?

Hi guys dont know whats up with my Galaxy S but my battery has been solid 100% for past three days now. dont know about you but my norm is, even on standy, i lose about 1% every 20-30mins at the very least.
but now it has been a good solid three days and my battery is still showing 100%, im assuming its a glitch of some sort? anyone else have anything similar happen?
oh i hav'nt plugged in the charger once, or plugged into computer, i hav'nt switched it off and on (scared i might disturb this magical state ). and yes i have actually been using the phone, texting, web serfing, etc.
its just usually even with light use of the phone, my battery is pretty much dead by the end of day one, but here i am day three and still 100%, wtf?
anyone else come across this phenomenon?
Unlimited energy?
Good job Samsung.
How do I obtain said glitch?
lol i dont know whats going on, but it's right here infornt of me! still 100%! day three and counting!
but just to mention, my battery was always quite dodgy. sometimes i would lose upto 5% battery in 30 minutes on standy!, to get a good battery state i used to turn the phone on and off until i reached my norm of about 1% loss in about 30 mins standby. but this is just silly, even if it is just a glitch that shows me 100% but may actually be 20% in reality, i just dont know how it is surviving 3 days straight without charging once.
Have you looked at your battery useage? It should show how long its been on for, I don't believe it! Samsung arent that great

Oh I've had this glitch before! Except In my case I was afraid the battery was broken so after about 15 hours or so of it showing 100%, I rebooted it and it showed me the accurate value.
Perhaps I should not have rebooted.

speak of the devil! it just switched off!
and right after i took a pic of the battery status screen aswell!
oh well, it was fun while it lasted, although something to note; battery seem to last about twice as long before it died out.

[Q] Battery problems... still...

Ok so I know I've posted about my battery before but I still can't get any relief.. I'm running JT .9 and geekniks 12/19 kernel.. the past two nights my battery drained 30% over an 8 hour period, with no one touching it! During both these nights I turned off Auto-Sync, and yes GPS and WIFI are both off..
Just now I had my phone charging and it was at 47%.. I rebooted my phone (just my normal procedure about once a day) and when it came back up a few seconds later it was at 69%!!! What gives?!?! Anyone have any ideas??
I have tried re calibrating the battery by deleting the battery stats method.. I tried calling verizon to get the battery replaced but was told that my battery is acting normal.. ive tried different kernels with no noticiable difference.. if i take my phone off the charger at 100% and send just a few text messages it will be down to 95% within minutes.. im at a loss.. I'll post pics of my battery use screen in a bit but throughout the night i only went 1% without a signal.
Maybe try *228 Option 2 ..... ??
I had a bout of some wicked battery drain and it was because I needed to update my roaming.....

I have the exact same problem. Battery will drain for no apparent reason. I even bought a brand new battery, with still no luck. When I reboot the phone, as you said, something it will jump up 20%. I finally got fed up charging 4 times a day and ordered a refurbished phone. I'll let you know how that one works out.

although Juice Defender turns off your 3g when the screen is off, it also turns on your 3g for 1 minute every 15 minutes, so push notifications will be seen every 15 minutes (which I find totally acceptable to dramatically raise my battery life)
Just an fyi in case you didn't know.

yeah i was aware of that but i also didnt notice my battery life improve enough to use it.. if i would have noticed a dramatic improve i would have kept it.
At first I didn't notice an increase either, but after a day or 2. I get over 50% battery now
I just started charing my phone again.. it was at 70%.. i rebooted my phone and it jumped 14% to 84%... is it possible that the battery meter is just not accurate and when I reboot my phone it recalibrates everything and displays a true reading?
I can't remember where I read it, but I read that the phone doesn't portray an accurate reading. . If you charge to a hundred percent, the phone reduces the amount of power coming in but still shows full till removed from the charger, then it drops fast. Supposedly once it gets down to a certain percentage it starts charging again in bursts. This could explain why rebooting changes your percentage since the OS is showing the inaccurate reading.
I don't know if this is true or not, just something I read.
There's an excellent explanation of this here on xda. The thread is called "Your battery gauge is lying to you (and why that's not such a bad thing)" & I wish I could remember who wrote it so I could give him credit.

I called VZW's Customer Service and told them about my issues and they sent me a refurbished one. Just got it today, and so far, I'm having the exact same issues.
I am only here because a friend of mine is looking to get a Fascinate and I was doing some research for him.
I have an Evo, and I gotta say, you only lost 30% in 8 hours? Lucky you! The Evo, when it first came out would only last about 8 hours off the charger from a full charge, without touching it. The state of things now is a lot better. I can go 16 hours off the charger and still have 70-50% battery left depending on how much I used it.
The biggest changes have been custom undervolted kernels with HAVS, CPU underclocking with screen off, and "SBC" which probably just stands for super battery charge.
The SBC kernels for the Evo fix the issue of the battery dropping to about 87% minutes after taking it off the charger. It changes the charging behavior after full charge, maintains a trickle charge to hold battery voltage at 4.2v instead of burst charging intermittently once "full"
You guys might want to have your kernel developers look over here and probably see if some secrets can be passed along:
http://forum.xda-developers.com/showthread.php?t=876590
There's a neverending cornucopia of battery improvements over in the Evo forum and I'd suggest you guys go make a search over there for "battery" because tons of the same fixes are going to apply here. Good luck

I had a lot of similiar issues with battery life, and I found different kernels and roms have a huge effect on the battery:
Every StupidFast kernel I tried would *significantly* increase battery drain over stock. I'm talking 4-5% per hour overnight with the phone idle and not being touched or doing anything whatsoever - no GPS, no Bluetooth, no WiFi, no apps running, just sitting there.
Every BlackHole ROM I tried would do pretty much the same, although not quite as drastic.
JT's SuperClean was consistently very good on the battery.
On DI01, I was using SuperClean .4 on the stock kernel and getting a solid 24 hours on a charge. With DJ05, there is no stock kernel, and I had issues with SuperClean and signal strength, so I'm using the 12/12 kernel with the stock rom (debloated) and I'm getting 72 hours on a charge with conservative use and easily 48 hours with moderate use.
If you're using StupidFast, I'd suggest flashing one of JT's kernels or stock (if you're still on DI01) and see what difference it makes.
I finally am getting decent battery life.. I did a clean wipe and installed black hole 2.4 with jt's 11/29 kernel and have noticed a great improvement! Only problem is I get the audio popping with this kernel but I'll live with that as long as my battery is better.

They are directly related. If your phone if constantly trying to find a signal then this will drain your battery. Are you rooted, or totally stock?

Insane Battery Life

I'm hitting 41 hours and still have 19% battery life. I noticed it took around 10 full charges before my phone started to get this great battery life. I've been using it as normal and even listened to howard stern for a couple of hours yesterday. Talked on the phone a bunch of times around 30 texts and even used my 4g for a few minutes. I've never had an andorid phone last this long for me even when I had my Optimus S which I thought was awesome.
Anyone else getting this awesome battery life? I'll post screen shots when its about dead as I dont want to plug the phone into usb to get the pics.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better after you try the things I've listed below. Note, I didnt have this great of battery life until 6 days after I purchased the phone and charged and discharged numerous times. The first few days the battery life was not good at all.
A little list of things to do, check and or disable;
1. Use spare parts and find out whats killing your battery ie partial wake usage, cpu etc.
2. Turn your window animations from all to only some animations
3. Turn off automatic display and keep it around 20-30%
4. I have auto sync off on all my appz (E-mail, Gmail, Facebook etc.). I update my E-mail and such manually.
5. Turn off data when not using it. I find data accounts for around 15-25% of juice used and thats just when on idle.
6. Only use widgets on the homescreen if you really have to (Running widgets use a lot of power over time)
7. Use Android Hackers tool from the market and it will break down how long your cpu was in a certain state. ie my cpu spent 65% at 245mhz and 28% at 806mhz.
8. Keep off 4G, Bluetooth, wirless networks for location and GPS if not using it (GPS uses less power than wireless networks and is more accurate anyway) I assigned Quick Settings to open when I hold down the search button. That makes it easy to enable/disable any of these setting within seconds.
9. Turn off google talk and make sure it doesnt sign in automatically (most people dont realise this)
10. Turn screen timeout to 15 or 30 seconds (if longer your phone can keep the display on accidentally while in your pocket if a button is pressed, wasting power)
11. Dont use a task killer unless its to kill an app you know drains your battery and therefore must be closed to save juice
12. Check your apps. Some apps keep using cpu etc because they were not programed correctly. (some appz I've found to drain my battery are; Yahoo Mail, Craigslist, AndTorrent and the market if a download is hung up. There are a few others I cant remember off the top of my head) If your phone is getting hot for no apparent reason this may be the cause.
13. Calibrate your battery by bump charging (charge your phone till its full while on, turn it off and charge till its full again. Then bump charge it around 5-7 times) Wipe battery stats if applicable. If you have a car charger, plug your phone in on the way to work to account for the little bit of drain that occurs once the phone is fully charged yet still on the charger.
Remember you can get china made batteries for very cheap. I paid $12 for 2 batteries and a wall charger off ebay. This phone uses the same batteries as the Hero and Evo by the way.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
I noticed Yahoo mail and Craigs list apps I downloaded from the market have a memory/cpu leak that kills your phone super fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better. Note to that I didnt have this great of battery life until 6 days after I purchased the phone. The first few days the battery life was not good at all.

yahoo mail DESTROYED my battery life on my hero so i havent used it in forever...sad to see it still had that problem....also I stopped using any battery widgets that show the exact percentage (as these are usually wrong anyway) and went back to using stock browser (Miren browser, while I really liked it, was eating my...)....i now check my battery through the settings....I was having varying battery life but after recalibrating by letting it die all the way then charging it up full i most recently got like 30 hours off the charger with moderate use and got down to 10%....coulda probably squeezed out a few more hours too if i left it idle....not too bad

I find that Battery indicator doesnt draw much power if any as I've always used it and never had a problem. The maker of the app states it uses no extra power. I love the circular battery indicator version found in the market. Its not a widget, it stays in the upper left corner of your notification bar. You should give it a try.
Phone doesn't get hot. I've started from scratch twice, I've ##DATA# reset. I had terrible service and data speeds before I did that and it did a number on my battery. Now it'd fine, but it just drains while doing nothing.
I never use task killers or auto sync, I live with spare parts and and monitor it, no real partial wake usage to speak of. I know how to save battery, my hero get 20+ hours with use and auto-sync on.
I'm thinking my battery might be bad. Feels like your talking down to me too, captain.

I haven't had mine a week yet, but atm I'm not getting half the battery life I did outta my Hero running AOSP's Gingerbread alpha.
I'm blaming the crap bloat that's part of the stock ROM.
With the display set to 15-20% I've got the display accounting for 69% of the battery usage. :/
Turning off sync is not an option and I feel defeats the purpose of a smart phone. Additionally, I fail to see the point in paying for 4G and not using it. (I do turn it off if I'm out of area for it or don't expect to be using much data.)
So thus far I'm disappointed in the battery life... but still think it'll improve vastly once rooted and cleaned up.
EDIT: Just did a test running Angry Birds for about 10 minutes... maybe 15. It ate up 9% of the battery in that time. Added another 1% to the display usage.

I'm just trying to give advice so that other people understand what to do to get the most out of the battery. This wasnt meant to be just directed to you. Sorry for trying to help you out, Captain.

Miren's latest update last week is supposed to have "reduced battery usage". I've had no problems. Maybe time to come back to the Light..?
I was able to hit the 48 hour mark with light use.

hey that's really impressive. I thought my 20 hours battery life was pretty good...kudos to you.
def getting better bat supply. especially from my hero which only lasted about 6-8 hours, just got my shift yesterday afternoon. from a full charge: Constant texting, facebook, Zenonia 2 (Downloaded wifi), Snes emu + 11 roms (3G), and customizing it to my hearts content. almost 12 hrs later had 20% until i plugged it up at work.
so far this thing is a golden brick to me
Just out of curiosity, how do you calibrate the battery? Just in case my battery life doesn't match the reports (I know my luck )

Its under # 13 on my 3rd post.
getting great battery life isn't that surprising given you've got a 1500mah battery much like the evo and epic however 48 hours is rather impressive.
Sent from my cm7 Evo 4G!
Working on calibrating my wifes battery and damn this thing is hard to kill. Even with with everything running for 5 hours its still over 20% finally decided to bring out the big guns. Turned on navigation and the flashlight. I'll post when I see the battery life after calibration.
Sent from my cm7 Evo 4G!
Edit: Phone plugged in at 7:53pm PST. Now to see how long it takes to charge.
Edit #2: Phone finally fully charged almost an hour after my evo finished its 0 to 100 at 12:19am
Edit #3: Holy F***. This phone takes forever to die and to die. Finally on the second off charge. I wouldn't still be doing this but for the fact that its saturday.
