Strange battery level reading

My phone was reading 20% battery left after a long day of using it when I rebooted it. When it started back up the battery level read at 50% and didn't drop back down to the 20% that it read just minutes earlier before I restarted it. Has anyone else seen this kind of strange behavior?

I see the same thing. I was down to 30 percent after 8 hours. Then i restarted the phone and it was up to 70% and its lasting another 8 hours. Great battery life, but the indicator sucks. To my understanding, that will be getting fix with the OTA later today

Yeah, this seems to be happening.. I just saw this happen to a friend and of course to me, multiple times. It seems to be cool. It's literally amazing you ask me. It's just about to die and you reboot and your back up to the top. Hmm.. It's not like our battery is going bad, I mean i average out way more than any android i have EVER used, then reboot and get more, whew, this is really the best "droid" ever!

Yep, I've seen it a number of times now. At the very least it makes planning ahead impossible. Am I really down to 30%, or will I have 80% after a reboot (grrr).
I've also seen the converse of this,where 20% drops off the cliff. Goes from 20% to 5% within a couple minutes.
Will certainly be great if the patch fixes this. Not at all clear from that cryptic leaked updates list.

Yes same issue. If you reboot it always thinks the battery is higher than it is.

after the update Im still have the indicator problem. sucks

Mine's been fine after the update, except for the first reboot immediately afterwords, which I assume was just to correct the pre-update value. I've probably rebooted 3 or 4 times since, and have not seen the level jump. Hope that keeps up.

Wholy crap gingerbread has awful battery

I wouldn't even say I use my phone frequently. When I used the miui or however it's spelt rom I would have 60 percent to 30 remaining each day. On gingerbread? I'm down to 15 percent every day and every night my phone has shut off due to lack of battery.
Isn't there any rom with excellent battery life? That's all I want, I use my phone for tethering.

i put CM7-RC2 on my device yesterday and it's the best battery life i've ever gotten.

Gb battery life owns, u got something else going on

No he doesn't, i've measured religiously since the original nexus shipments and this is by far the worst

My battery was really bad but now it seems to last me 10hrs & up which is weird for a phone to last me that long. I really think theirs an app or bug running the battery crazy I don't use any task managers. Their was a thread somewhere saying to run your phone on recovery mode and to press on the reboot/restart and battery get better I did that so maybe it does work but I highly doubt it.

I can vouch for poor battery too. I am on CM7 RC2 and I can't even make it through a day with light use. By light use, I mean practally not using the phone at all.

My battery life seems to be better than ever. Some 10-20 percentage units more left in the evenings all down the line.
Edit: Stock GB, no task managers.

I agree. Gingerbread has been nothing short of AMAZING for my battery life. The battery life is so good now that I stopped using my spare battery altogether!

Did you happen to do an Update or a full install when you got gingerbread?
Some suggest that it's due to the update process.. so you might want to try a full install:

Remember to wipe your cache first..

What i noticed is taht custom roms use more battery than stock rom. this is for me i don't say that it is like this for everyone. But with gigerbread i got the best battery life. i also think using apps from SD uses also a lot of battery life, but again i have no other choice to low on memory.

bug
I had the same problem. I am on stock gb.
Just set wifi sleep policy to never. It will last 2 days after that. It is definetly a bug.

Seems to be a real mixed bag with GB on N1's. Lots of people saying "better battery" many others, myself included, reporting much worse. For me, I experienced very poor battery life right from updating to the stock GB using the singned passion .zip file. Even did a factory reset, and only reinstalled my daily used apps and it made little difference, then I went back onto a MIUI rom for a few days and battery life was wonderful again.
Then early this week I flashed to CM7 RC2, and for two days battery life was the worst I've ever had.
Had been seeing a few comments on different forums of people who had the same problem swearing black and blue that after they changed the wifi sleep policy to "always on" their battery life improved dramatically on Gingerbread.
I know if sounds backwards, and that is why I was sceptical for ages, but last night I made the change to see if it would make a difference for me today and all I can say is WOW!!! Phone had a real test today as I started work really early. As of right now the phone has been off charge for 16 hours.
Half a dozen or more voice calls, minimal text, my usual wifi and 3g data, about 10 min of streaming video over wifi and about 1/2 hour in total running Navigation.
There is no way in hell my phone would have done all that and even lasted me 8 hours prior to changing the wifi sleep policy - so I think there is definitely something in it.
As for the ppl who aren't noticing bad battery, maybe they already had theirs set this way - or maybe it's an issue only effecting certain batches of devices (like the wifi reconnect issue which seemed to be pretty common pre froyo)

it /WAS/ terrible at first. Really, really dire, but it's back to what it used to be, even better now perhaps.
To the OP, do you have WIFI turned on still? I used to leave it turned on and it didn't ever knock down battery as it was going to sleep and not coming back, so wasn't a drain. GB appears to have fixed this, and it was staying on, thrashing the battery.
Turning it off and turning it on as needed only, battery life is now fine.
Do you have WIFI Turned on? Bluetooth? For now, to try and test what's happening, turn off 3g, wifi, bluetooth, automatic date/time sync, and JUST use it as a phone for a day. See what % you're at at the end of the day.
Then we can take it from there.
But I'd be pretty certain that it's wifi related, in that it's now working as it should be, we just got used to it being broken before.

My phone on cm7 rc2 has worse battery than I used to have with wildmonks kernel and cm6.1. Yesterday, the phone was barely used until 8 o'clock at night. It was at 45 percent. After an hour medium use, its gotten down to 23 so I had to plug in the phone....the easiest fix? Keep a charger In the car!
Sent from my Xoom using XDA App

Using stock Gingerbread and I can say that my battery life is decent, better than Froyo for sure. The phone lasts longer than 16 hours and I use bluetooth to listen to music for 1.5 hrs on my commute home. By the time I get home after a long day (8pm'ish), I still have about 20 to 30% left.

I have no wifi no bluetooth no gps and a dim screen.
Tis is seriously crappy battery life.
Does anyone think they can link me to a good miui rom. For me, it seems that gb just wont work.
I am running stock gb then i flashed the root and my boot loader is unlocked.

Listen to this person!
For some reason, since 2.3.3, if you have your Wifi policy to sleep when the screen is off, Android will rip through your battery. You'll notice Android OS taking all the battery on the status page.
Set the sleep policy to never and you get better battery life again. Turn off Wifi manually when you're not using it, even better. Until somebody fixes this bug, I guess it's the only workaround we've got.
More info: check issue 15057 on code.google.com - cant post link due to the newness of this account.

Same here on shorter battery life my nexus one as well post gingerbread ota... I will look into detailed system processes and try to find out why...

Log into latitude and log out. Every time there is a map update it defaults to being a battery draining monster. But in essence. Something to do with maps link to latitude (which i don't even use) breaks my phones battery life.

Galaxy note update notification 26th July

Hi
This morning 26th on my note I had an OTA notification. Since I had no Wifi, I cancelled it. Now, when I do a manual check, it says 'no updates available'. I already have 4.04 (XXLRG) from an update a couple of weeks ago so it wasn't that.
Any idea what it might have been?
Hoping for some Jelly Bean soon since I like it on my N7.
Nigel

Omg. Seriously hoping this is foreshadowing the release of jellybean for the note...
Come on Sammy!!

Most likely not jb but to remove search the phone capability

Installing that much (really, any!) crapware along with updates is not cool...
But give me Jelly Bean quickly and I'll forgive you, Samsung.

So. Anyone know if this update fixed the battery problem many have? And fixed the issue of bricking the phone when hard reset?

The OP just said that all it did was install a bunch of crapware.
Nothing else.

And it's improved the performance..

Now now....can't use this without "value added software" because your user experience won't be as good

I got this update yesterday. However I can't find the apps mantioned here. It only said "Improved performance". I don't know what they mean. I have had the problems with the battery. I had to either pull the battery for a minute or two, or I had to switch on power saving mode right after charging and leave it on for some minutes before turning off powersaving. I had to do this every time I charged the phone, or else it would not go into deep sleep. It would stay on 200MHz, and drain the battery in a matter of hours.
However, this morning I saw (using CPU Spy) that the phone had charged all night using 200MHz (this might be normal. I don't know this). I tryed to just pull the charger, without doing the steps mentioned above. And i see now, a couple of hours later, that the phone has gone into deep sleep since I pulled the charger.
It might be too early to draw conclutions on this, but it looks promising so far.
I have found no info about the update yesterday. I hope its possible to hard reset the phone without bricking it now, but I don't know.
I will keep monitoring the phone, and let you know.

IIRC the phone doesn't charge during deep sleep, so clocked at 200 while charging should be normal.

That is normal and always was.
After you pull the charger it takes few minutes and the note goes into deep sleep.

I explained badly I think. I have used the CPU Spy for some time now, and i have seen that the cpu use 200MHz when it charging. Good to know this is normal. The big difference this morning was that when I took the phone off the charger, it went into deep sleep. It hasn't done that for a long time. Before the update, it went on using 200MHz after charging, when it was supposed to go into deep sleep. The only thing I could do to get it into deep sleep, was to pull the battery og use battery saver for a few mins.
I just hope they have fixed the brick problem when doing a hard reset too!

Yehh. I asked customer support what the update was, and if they fixed the battery problem and brick problem. They answered that I had to hard reset to fix the battery problem and the update was "improved performance". So I guess I either have to live with a bad battery or bricked phone hehe. Kinda hopeless imo. Anyways, the battery still works good after update :good:

Anyone have bad battery life on g2? Any fixes?

Has anyone been experiencing bad battery life on the g2? When i first got it a month ago it was amazing easily getting 50+ hours with about 6 hours screen time. But over time its been getting worse. I already did the whole stopping the carrier iq and all that, it still doesnt help much. Now when i go to sleep and wake up 7-8 hours later my battery drains 50% or something like that for no reason, no wifi or anything on or synced. I did see some posts about people experiencing bad battery, this phone is supposed to have amazing battery life whats going on? I rooted my phone, still on stock rom, wondering if anyone has fixed their battery issue. Would installing a new rom like aeon v3 help improve battery like its supposed to be? Its getting frustrating, my gs4 had worse battery but at least the standby times werent as bad as they are on my g2. Any fixes for this?

There has to be something running in the back ground draining battery. If not try finding a battery Conditioning Application

Based on the above it could be a few things.
If you want to check a few things on the phone side you can:
- install GSAM Battery and let it keep an eye on what's actually using your juice. Then either remove, modify, adjust settings, etc, for whatever is using it. If it's an app... delete it. Reinstall it.
- You can try a factory reset
If neither fix it then you can try another ROM, but if your battery is just as bad with a factory reset I'd lean towards the battery. Maybe you have some bad cells.
I've had mine for a bit, and I only lose a little bit if not touched overnight.
My current setup:
- Madhi 4.4 KK ROM (1/18 build)
- Obviously rooted with the above
- Greenify on all my non-necessary apps (hangouts, weather and one other app spared from this)
- All my apps auto-sync features are disabled since I just run it once in a while, and things like mail / etc I don't need push anyways
I get pretty solid life even after a few moths of use now.

first, install betterbatterystats and look for wakelocks, try reseting the device. batterylife also depends on how you use the phone...i can get 9hrs on screen time reading books with still 15% left or drain it in 3-4hrs playing games.

Yes i have downloaded and used gsam battery app. I dont see anything unusual in my stats, also using better battery stats, its been in deep sleep for most of the time, and it doesnt say the phone was on or running when the screen was off. But for some reason i wake up and my battery is decreased by 50% again....I am using greenify and hibernating alot of those annoying apps. I am stopping apps that are running . And on the phones battery manager android system is first with 34% but it says its only been running 11min, and no gps is listed. And my screen on time was 2 hours those are what i foudn when i woke up with 20% left, at night it was 70%. I seriously think my phone is messed up when im using it its not that bad, but for some reason when i go to sleep and leave it alone it dies for no reason....

I definetly would try it. Also you could try different kernel. But its beginning to sound like there could be a defect in your battery. If nothing helps i would send the phone to LG and let the battery replace. You are still in warranty, right?

my battery has a problem too..
when my phone is idle sometimes the battery level increases by 1 or 2.
when im playing heavy games like gangstar 4 the battery decreases every 2 mins and the temperature reaches 40°C. and when im just browsing it decreases every 3-5 mins with a temperature of 34-36°C. and when im watching kuroko no basket (wifi off) every episode just consume 2-3% of the battery (24 mins. = 2-3%)
and the temperature is about 28-30°C.
I think my battery drain problem depends on the temperature

Samsung Note 4 N910C battery drain

Hello and Happy New Year to all,
*
I came across an issue with my Note's (N910C) battery today and I would like your opinion on it.
*
A quick background:
*
The phone has never been rooted.
9-10 months ago I downloaded an official firmware (6.0.1) which I flashed via Odin and it began to drain the battery very fast, killing the phone in less than a day.
I got a new battery, but the problem was still there.
Eventually I tried another firmware which worked nicely and consumption returned to normal levels. Since then, I had no problems whatsoever.
Yesterday night I got a notification to update. I had already done another two in the past - if I'm not mistaken - , without noticeable difference.
I did the update overnight and I removed the charging cable in the morning. It seemed that it was a little warmer than usual, but I did not pay attention.
The battery percentage was reducing at the rate of 1% per minute and it died within 2 hours.
I checked battery info, nothing abnormal.
I have two questions:
*
1. Does anyone have similar experience with this model (or other)?
2. If I reinstall the previous firmware, normally the problem should be fixed, right? I mean it started after an official update which AFAIK affects native apps only.
*
Thank you in advance

I have noticed on my Note 4, after upgrading to marshmallow, the battery drained like crazy too. It would drain 10-20% when I use it for 20 mins or so. The battery that I'm using is a 'new' one that I bought just about a year ago although the problem still occurred when it was fairly new.
I'm speculating that there might be some sort of battery or software issue with marshmallow as the original battery that came with the phone also had the same issue. It would drain fairly quickly until one day it just stopped working and would boot loop until I plugged it in to the charger.
Ever since marshmallow, I have never seen my battery get to 15% before switching off completely. Sometimes even 45% lol.

I had a faulty N910F and got another (used) one and it's had occasional forced closes at between 15-20%. This worries me that it might go the way of the old one where it developed the issues with it freezing and the frequent reboots....does yours exhibit any other issues?

Yes. Unfortunately. Currently, it would just die halfway even when I'm at 50%? That's the highest that I've noticed. So I had to charge it up for a bit maybe to 60% and it would be fine before dying around the 20+ - 40% mark. Previously, the original battery that came with the phone had this weird issue where the battery won't hold any charge even when it's fully charged. Like it will go to a bootloop when I've unplugged it even though it's at 100%. When I bought the new, current battery I noticed that it would still die off at 15-20% and the original battery became bloated a few months later.
Are you using any custom roms? The bootloops and freezing could be related to using some custom roms. I changed from a N7 port to a deodexed stock rom and the frequency of the freezing and reboots just plummeted. Reboots only happening when the battery is close to dying.

Ah right, so you had only the reboots, nothing else? That's fair enough.
No, it's nothing at all to do with the ROM. I'm stock but LOTS of people have had the same issue. As it stands, the only way to fix it is to get a new mobo :crying:

Well besides the usual overheating that's related to our snapdragon CPU, nothing much but mostly battery issues.
Although there is thread that I'm following that promises to fix the 15-20% issue. Checking their method to see if it works or not

I did the update overnight and I removed the charging cable in the morning. It seemed that it was a little warmer than usual, but I did not pay attention.
The battery percentage was reducing at the rate of 1% per minute and it died within 2 hours.
I checked battery info, nothing abnormal.
I have two questions:
*
1. Does anyone have similar experience with this model (or other)?
2. If I reinstall the previous firmware, normally the problem should be fixed, right? I mean it started after an official update which AFAIK affects native apps only.
*
Thank you in advance

hey can you give me the link of that firmware that improved your battery life

I had a similar problem with fast battery drain - did a factory reset and it's back to normal. Make sure you're using a battery from a reputable source like RavPower (don't think there are any genuine Samsung ones left and Anker stopped making them).
