[Q] Battery problem

Hey, I just bought an used HTC G1 from ebay. When I'm trying to use it, the phone just turns off with no warnning and with 80%~ of charge with only 10 minutes of use.. If I wait a little bit, I'm able to turn it on again and see that it has 80% of charge, but keep turning off.
I'm very confused because it just charge for a few minutes and the green led comes on.
Well, the phone was first with android 1.6 and then I flash cyanogen 2.2 but its the same think, and all the apps that I use to see the battery status indicate "good"
is the battery old or there's anything i'm missing?
Thank you!
(sorry for any english mistakes )

My two G1's I had same problems, the replacement batteries fixed the random shutoff of the phone.
Sounds like your battery is messed up. Did you see if the battery is swollen or a odd shape?
You can get a replacement on Amazon. You can get a two for one sale if you look around.

Oh im having the same problem and i notice my battery does have a lil bulge on the top it so i guess i will try a new battery i hope it works

I had problems with the battery too, if the battery is bumped, don't use it, it may explode and hurt you.
I cannot post links but I recommend the mugen battery.
I have it and it's working great.

it's the battery..u'll see that u can use it while it's plugged to charge.....
and when not...bang boom-off!!!
had the same probs....switched to a 2850mAh battery
and also, dont use any random charger!!!

Solid amber then nothing

Any help here appreciAted all the sudden my shift won't charge I plug it in and get a solid amber light for 5 seconds then nothing. Tried various chargers Anne removing as still nothing.

try a battery pull and try again

Tried removing battery SDcard still solid then off

Check the charger port. If you keep your phone in your pocket like I do, you get lint build up. I've already had to clean mine out twice. I used compressed air, and was very careful.

Tried charger port looks clean used air did try to turn it on while amber light was solid iT began to then shut off

try a different mini usb cord, see if that works. It could be a bad cord...

Also tried different cord combinations USB>AC USB>Pc etc to have same result plug in a few seconds Later I get solid amber for about 5 seconds then it goes off. Have to unplug and remove battery and replugin to get it to recognize anything again.

Can you clear battery stats? Long shot, but you never know...

All I can do is try a power on during that 5 seconds. Which initiates a power up but it still shuts off as soon as either the white HTC screen starts or if I try recovery as soon as the Boofloader screen where it gives you boot options and shows sff that screen don't know correct name for it. Either way all I get is a quick flash of either screen when it attempts to boot then shuts off.

This is a longshot too try plugging it in and leave it for a couple hours or if somebody you know has a hero or og evo charge your batt in it for a hour or 2 then see if it is your battery or the phone. I remember reading somewhere if you completely kill those li-lon batteries it messes them up and possibly the phone too. You didn't run it completely down did you?
Edit: you may have to flip the hero or evo's battery over to make the contgacts match up,not to worry it'll work cuz I'm running my heroi 1700mha battery in my shift now.

Themikmik.com has a thread on battery calibration, one of the options is to pull the battery during bootup. This clears the battery stats folder.
Ought to see if your local sprint store has a battery you can test b4 you buy, may be that simple. I would avoid the full service stores, maybe a mall kiosk?

+1 You might want to try a different Battery. These batteries do not like being run all the way down to nothing. Had an issue once where I thought it was a rogue app running the battery down really quick. It wasn't, I had let the battery drain down to nothing one to many times. Fresh battery cured the issue. Actually got it from Sprint for free. Walked in said my battery was no good and they gave me a new one, no questions .

HERE is the thread on the MikMIk for Battery Calibration.

Issue resolved after 3 hrs at retail seems battery boost is all it. Needed so far although CSR tried to blame it on water damage. Saying litmus near USB port was pink which they refuses to show me when I asked to see It knowing that it's never been near moisture other then the humidity in the air. Let's hope this does it.

Thanks for finding that link prboy, I didn't have time to hunt it down earlier.
Anyone mind tellin me what a battery boost is? New to me.
Also, according to HTC, we should be completely killing the battery once a month as maintenence. Has this proven detrimental to the life of the cell?
Sent from my Shifty Speed Brick using xda premium

No proplem, help when I can. No idea what a battery boost is . But as for killing the battery once a month. Well that's a whole different can of worms . There are different schools of thought on that. Some say it's really bad, because it kills the cells. Others say it's necessary to kill it in order to retrain it. Just Google it, but be prepared to read through a lot of info. Personaly ( IMO not that it means a damm thing ) I don't believe in the whole drain it dead phiosophy. But that's just my opinion

I used to manage batteries plus... Lithium ion batteries are the best because there arent memory gimmicks... It is not a bad thing to drain it down to 1 - 2 percent. I personally dont drain down all the way because I had an odd experience with my phone not being able to turn on (no recovery, nothing!) for about 2 hours... I thought it bricked somehow, so I let it alone for an hour on the charger and it magically (thankfully) turned on when I tried... It freaked me out so I never let my phone's battery die...
It is always a good idea to cycle the battery but the most imporatant thing to do with any cell phone battery is to charge it uninterrupted for 24 hours before using it...

Battery 0% - Unkown

Hi,
My battery info screen is always showing 0% - Unknown. I´ve tried different charging options but with no success.
The battery is charging and when I connect the Nexus 7 to the adapter/pc is says charging - 0% when locked.
Any help is appreciated.
Thanks

Had the same problem. It was not ROM specific. Even though the reading said 0 it was still charging normally (as far as I could tell).
I called Google (I bought my Nexus 7 from the Play Store) and they replaced it. I think that the battery sensor was bad.

Charge your battery to 100 percent, for the best that you can assume as 100 percent - about 3 hours, - and then run this program https://play.google.com/store/apps/details?id=com.nema.batterycalibration root required

Reflash kernel

Just to let everyone know I tried both that app and clearing battery sats in CWM, neither did anything. I even ran it dead and then fully charged with no change. The OP may have a different problem but in my case I definitely think it was a hardware sensor issue.
Sent from my LG-P999 using xda app-developers app

Um, weird, I came home after leaving my tablet on my desk all day at home, with about 35% battery.
It was dead. Like really dead. Dead dead. I don't know if it should've run down 35% totally idle; I'd left it for 3 days before without a problem.
Now when I plugged it in, it turned straight on. Google Screen -> Lock Screen. No colored X.
Showed 0% for 10 minutes. The battery graph was especially weird. For one thing, it had locked the stats and showed as still on battery basically. For another, it showed going from the low end of green to instantly dropping to 0%, red. Unplugged it, and it died instantly.
I'm letting it charge now with it off. Quick power button press shows the charging indicator thing.
I actually have an RMA out for this one for the touch screen issues, so it doesn't matter, but still... weird.

battery sensor/calibration issues
Old thread but I thought I'd add to it for other people with the same problem.
I have basically have the same issue on a stock, rooted 16GB Nexus 7. It's highly intermittent.
It first reared it's head about a month after I got the device (in Aug 2012), on the original firmware. My nexus 7 wouldn't (appear to) charge past 25% and would shut itself off after being on for only a few hours. I spent a day trying to fix it, including wiping the device, but nothing worked. Then magically, a few days later, the problem was gone.
The Nexus 7 worked fine for another month or so and then one day, after having charged it for several hours, I noticed that it was reporting a 0% charge. (Firmware was still stock but had been updated) This time it didn't power off, it just misreported it's charge. I could still run it for 10 hours or so, even though it said that it had a 0% charge and that I should connect the charger. I tried the "battery calibrator" mentioned in this thread which didn't seem to work but the next day, the device reported it had a charge. It's been randomly fluctuating between reporting 0% and a having charge every since. Sometimes it works fine for several days but then it will say 0% again.
It hasn't really affected my use of the device but it can be inconvenient not knowing how much charge you have left. Today I finally called Google and explained the problem and they promptly offered to exchange it. Hopefully this is not a design flaw but a faulty component from bad batch..

There's more than a good bit of bad advice in this thread. That anyone would waste people's time by recommending a ”battery calibration” app or to wipe battery stats is disheartening, as it is widely known that they have no correlation to battery indication.
More often than not, it seems, this problem with the N7 involves the battery connector not being properly seated.

I'm also having a similar problem, though when my nexus 7 completely dies from the battery I plug in and right away power back up and when it comes to the home screen with 0-1% charge it right away powers down. I tried leaving it off while pluged in let it charge for 5 mins and then power back up again till I see it have a minimum amount of charge, it seems to work not sure if its ROM or kernel related, I'll keep an eye on it.
There's a helpful article that seems to help other nexus 7 users, hope this helps

I have the same problem with my nexus 7 3g.
Factory reset does not help.
Finally open the back cover (quite easy) and found that the battery cable connector is loose. So I tightened and my tablet is well again.
Hope this help.

Yeah what worked for me was to also unplug my battery. Seemed to correct itself after that. Mine would shut off showing a charge of 60%.

Does the back just unsnap like a regular battery door?

I have issues sometimes. Like the other night it charged all night and when I woke up it was fine, turn off the alarm on it and had breakfast. Came back and it wouldn't come on. Tried all I could without taking it apart. Ended up removing the back cover, unplugging the battery for ten seconds and then it worked fine. Battery was at 100% once it booted up.

Use your fingernail to get between it and the chassis. It pops off pretty easy. Just be careful. I'm sure YouTube has a few videos showing it.

Hi.. I Have the same model and I had the same problem...
I made the turn off method (https://plus.google.com/+DerekRoss/posts/563EVVEPMDS) and did not work...
I rooted my Nexus to calibrate the Battery (http://forum.xda-developers.com/showthread.php?t=1838429) and did not work.
But the in my case the most simple solution works : Unplug /plug the Battery (http://productforums.google.com/forum/#!msg/mobile/Knrn4DThksg/ovuWYHUytZ0J).

N7 JB 4.2 strange charging issue

My stock unrooted 16gb n7 received the 4.2 update this morning, all has been fine until this evening when it needed charge.
It often gets plugged into a htc phone charger, which has worked fine since i bought the tab a few months ago until today, its a 1amp charger so it takes ages to charge, but thats fine as it is plugged in until the morning normally.
So i plugin as normal, and come back after setting up google play music on my desktop pc, and i see the unit rebooting showing the glowing X. The screen goes blank and is unresponsive, eventually the google logo appears and it boots normally (its still plugged in btw), after unlocking the screen goes mental after maybe 5 seconds with random noise on it, then goes black.
So i unplug and use the genuine asus charger and cable, it does the same twice over, reboot, freeze, long wait then reboot.
I have now left it on charge using the asus charger and it seems to be ok now
Have google changed some charging requirements? Anyone else seen this?

Not sure, but my nexus 7 on Android 4.2 charges like 35% slower than did with 4.1.2..... what the hell did they do??

Funny you mention that, i might agree with you there
The N7 seems fine today, i did make a couple of videos of it misbehaving last night, watching back my circle battery widget app jumps from 16% to 0% battery just before it goes blank, indicating it might have simply run flat but thought it still had 16% battery?
Wonder if they have changed the battery meter scaling?
I think i will run it flat and check it shuts down properly like it used to

Hi dexterslab,
On a side note when you update to 4.2 were you already rooted and did you have superSU version0.98 installed? I have been reading other posts in this forum that folks have been rooted, superSU installed and the update has completely crashed their N7. ANy info would be greatly appreciated.
Thanks,
JBIRD

Its still as stock, locked and unrooted

I've noticed slower charging since the 4.2 update too - did a quick Google search and landed here. Using the same genuine Asus charger and generic cable that I did before the update, and I would agree with the roughly 35% slower estimate.

Are you using the new Daydream feature (you can find it in the display settings). If yes this may be the cause of slower charging, because it doesn't turn of the display.

Daydream is off.
Tbh, now it seems to have settled down i think maybe charging time is pretty much the same as it was. The whole debacle seems to be a complete non-event in hindsight!

No Daydream for me.

Mine is stock and unrooted. After the update I'm having the same charging issues. Incredibly slower charging. It's been plugged in for 6 hours now and it's at 80%. I did play a bit of pandora for about 30minutes but it was still plugged in. Other than that I haven't touched it other than to check the level. I turned daydream. Let's see if that help though I doubt it.

i think when you install the 4.2 update it does a battery stat wipe. this could produce the battery jumping from 16%-0% i reset the battery stats on my gt-i9003 the other day charged, its went from 100% - 40% instantly after about 2 charge cycles it should go back to normal.
it would also explain the battery seeming to take longer to charge, its just the voltage counter resetting itself. it might even in some cases charge faster....then run out quicker....
charge- discharge about 3 times and it should go back to norm.:good:

Agreed, phones seem to be more universally compatible when it comes to charges.
Charge a tab with the wrong charger n you'll make up with a melted Nexus 7

i think its a part of certain regulations now that mobile phones needs to have an internal capacitor/transformer to make sure of this problem, as people usually run out of charge on the go and use other chargers as long as the connector fits and it begins charging, most of us including me are probably guilty of plugging a charger in, seeing its charging and thinking *yay it works fine* walking away and not really understanding what slow-fast damage can be caused to the device/battery.
for tabs 30% i would say dont have this feature:good: especially the Chinese ones. ? <no racial offence intended> you guys know what im on about.

My Nexus 7 worked great before upgrading to 4.2. Now it can't charge while I'm using it... The battery just goes up and down as I'm surfing the web, if I load a lot of pages, it goes down, if I read a lot, it goes up... But if I try to watch a floating video while surfing the web, it just goes down... There is definitely a problem! Here is a screenshot... I'm using the original charger and cable...

Wiping battery stats does absolutely nothing that affects reported battery charge level. That wives' tale was long ago debunked by a member of Google's Android team. The one and only thing you are wiping is a list of apps that have operated on battery since unplugging after the last complete charge. This in no way, shape, or form affects reported charge or has any effect on battery life whatsoever.

LIKE I AM SAYING MY FRIEND,
actually the battery stats ARE WHAT THE GOOGLE DEV SAID is what gives you accurate readings it doesn't increase your battery life . i never said that it will, so please don't police me,.
heres the comment
This file [batterystats.bin] is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings. That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
when you flash a new firmware, the system must calibrate as there are no previous readings from the bstat file right?.,these are the readings that help the system produce the reported battery charge. its what it does to give you those readings, i was guiding the above member to wait and run a few cycles for readings to be more accurate i never said his battery was dead.
kinda why pretty much EVERYONE mentions after flashing a new firmware on most device they have a few days of battery "up-n-downs"= counter reset/data collection/last battstat file wiped.
cheers:good:

Read her entire dissertation, and you will see that it does not pertain to reported charge level. She explicitly states that batterystats.bin has no bearing on reported charge level. Interesting that you left out the portions of her post immediately prior to, and immediately following, the part of her post that you quoted... you know, the ones where she states, and then restates, that nothing in batterystats.bin affects the reported charge level? Also, the reason the battery seems more stable a few days after flashing new firmware is the kernel itself settling, not the OS.

[Q] ROM problem or my battery?

Currently using Stepp_aospX 1.0.0-MR2.
When I'm watching a 30 minute YouTube video, the battery goes down by about 45%. When I turn off the phone and turn it back on, the battery jumps back up about 20-30%. Now I'm wondering if this is a problem with by battery or with the ROM.
Can anyone else get this issue to occur on their phone?

probably the battery, how old is the battery? Any water damage?

I'm using the same battery the phone came with (bought new 2 years ago). No water damage.

Two years is a lot of time bud, thats the problem right there.. Batteries wear down, imagine how many times that battery has gone from 0% to 100% in the course of 2 years..

Yeah, it sounds like you need a new battery. Anker makes great ones, they aren't too expensive, just buy them off of amazon. Before you do that, take out the battery and check for lumps or stuff like that.
Again, there is a 90% change that you just need a new battery

That's what I was afraid of. No lumps on the battery (thankfully). Probably not going to buy a new battery though. Waiting for a good deal on a Galaxy SIII or Nexus 4.
Thanks guys.

Someone once said to charge the battery to 100% then clear battery stats then drain it down to almost 0% then clear stats again. then charge it back to 100% in one sitting. that helps me sometimes when flashing an old backup and the percentage jumps around after a reboot.

Thats a placebo. It really doesn't do very much. If you get random battery level jumps, its a sign that you need a new battery

Ive found that a lot of times you can't see it starting to bow, but if you spin it you can tell. If it just spins 90-180* then it's probably ok, but of it spins more than that it's bad. I grab the battery charger + 3 batteres from eBay for under $10. Now I just swap batteries rather than charge the phone.
