What is up with the battery life on 2.3.3?

After replacing the battery with a 1600 mah Seidio battery. I still get bad results. For example, during lunch today my phone was at 50% in my locker. After 4 hours, I was at 21%. My Sync, GPS, BT and Wifi are all OFF.
How is this possible?
I use to own a Nexus One and in 4 hours it would go down 2% with CM6. Is Gingerbread an issue here or does my phone need RMA repair?

2.3.3 gives me better battery than 2.1 or 2.2

superaosp from [email protected] stock kernel or redstars depends but cm7 and stock OTA gave me better battery than 2.2/2.1

I'm running stock 2.3.3 and battery life is by far the best over various android versions.

2.3.3 has some weird bug where every once in a while the system gets into a weird drain state like it doesnt go into deep sleep correctly. i just got hit with this last night. it does happen all the time, most of the time on 2.3.3 battery life is excellent. i will lose 6% over 8 hours. but when that awake bug DOES kick in, battery drops like yours did.
you just have to reboot and check it again, the bug likely will clear itself and you wont see it again, for a while.

yes, this is exactly what the bug is. sometimes randomly on GB the phone stays awake for no reason, for hours. but when this DOESNT happen, batteyr life is superb. i only get hit with this bug once a week or less.

I hope google resolves this issue! I was getting worried that I have a defective phone.

My N1 on 2.3.3 goes completely dead after 12hrs. I found the solution when doing a Google search. It's to go to Wifi Settings, Advanced, Wi-Fi sleep policy, and change it to Never. You'd think that would reduce battery life, but for some reason now my phone's battery life is very significantly improved. Now it's only down to about 30% after 19hrs when I put it on the charger.

It appears that 2.3.4 will address battery issues in Gingerbread.

That's pretty cool even though I've not had any major battery issues.
But improvements are always welcome
Here's a quote from your link:

I dont think its Gingerbread, ive used both stock and CM7 on my N1 and i was having good bat life on N1 stock gingerbread about 5-6 hours with heavy use, and with CM7 official rom i get 7-8 hours heavy use and up to 19 hours on days i barely use the phone, and on standby i can confirm 8 hours (while im asleep) it drains 6% by the time i wake up of course i do have it personalized and settings applied for bat savings.

I haven't encountered this bug with CM 7.0.3 (based on 2.3.3) but I found it very useful to let the phone just drain the battery completely once in a while (once in a few weeks) and than fully charge it.
After doing that, I can go through two days with regular usage of the device

I'm on CM 7.0.3, 2.3.3 and I'm only getting 13-15 hrs if I'm lucky. Wifi and bluetooth are off only syncing gmail and google contacts. I barely even touch my phone at work for 8 hrs and the battery life sucks.
Another weird thing is that once it gets to 15% left it just automatically dies and shuts down...very frustrating, I'm on the latest pershoot kernel too, the phone was given to me for free last month and it was originally purchased in Feb '10 so I just figure the battery is old and worn out.

No. Your battery is not aged, it just needs re-calibration.
One simple way is to re-calibrate your battery is to charge it when the phone is off or charge using a desktop charher, and you have to over-charge a bit - just leave the battery connecting to power source for an additional 1 hour or more, when the charging process has been completed.
This works every time for me.
Keep in mind that from time to time the battery may need to be re-calibrated again for peak performance.

Nexus S battery

Hi did anyone experiance this kind of battery consumption? 3days 14hours and 45min and still have like 7%?

Not personally, I use my phone too much to get that kind of life out of it. Based on what I know about the drain when it's screen off and sleeping, though, I think it's well within the realm of possibility with light use.

I get like 24 hours out of mine... with some light-moderate use... used to be better when I bought it but then after installing some apps it just starts degrading a bit I guess

Well, rechargable batteries do degrade over time, and the more apps you have on a device, generally the less time it will last on battery, partially because those that run in the background consume more system resources and partially because those that update data in the background will keep your phone "awake" more of the time.

If I wasn't using my phone and just let it idle (sync on, airplane mode off) I'd get like 12 days of battery life. That's what I like about the NxS, unlike other smartphones it does actually last longer when not used.

hi
i am getting around 10 to 12 hours. wifi always on. mostly watching youtube videos. netbrwosing. gaming.
2g phone calling
still i think i am getting reasonably good back up

Disabling wifi,gps,bluetooth and reducing screen brightness will improve battery life.

That's no issue, but working as intended.
Other phones are using the same technique, but they are hiding it by showing the 100% the phone never reached, that's why they drop to 95-97%ish right after unplugging and from there drain normally.

I experienced battery drowning after using app's like maps or latitude. I had to kill them manually, now I'm cleaning the phones memory regularly. That safes a lot of battery life for me on the one hand, but on the other hand loading app's isn't as fast as before.
It's the classical trade-off between battery life an usability. And 10-12 hours are normal for me if I'm using my phone a lot.

Well, depends on the manuf. if they want to "hide" it or not, they could also set 95% capacity as "100%" displayed. All batteries got a safety feature of some kind

Battery life gone down the drain after firmware upgrade

Hi guys,
A couple of weeks ago, Note II informed me of an upgrade. I did a bit of googling and found out it was to fix some exonys bug. Seemed pretty important so I did the upgrade post haste.
At first the battery life was atrocious (like a 50% drop). The same thing happened with my old iPhone 4 but everything reverted to normal within a week. So, I though maybe things are new and Android will fix itself up after some time.
How wrong was I ? LOL. My phone gives me just a day's worth of battery life. Earlier it was a solid two days. Which was why I justified carrying this brick of a phone. It is pretty ridiculous to see the battery drop by 30% at times in three or four hours (despite zero use).
Any suggestions to improve or remove the pathetic firmware upgrade.
1. Use the nova launcer
2. Auto brightness with the slider dragged to 1/3rd
3. 3G always on
4. The battery screen shows screen taking 70% of the battery! I have the auto off timer set to 15s the minimum.
Any suggestions guys? I am frustrated with this phone post the update. Thinking of switching back to the iPhone as atleast it gave me a day's pf juice in a much pocketable format.:crying:

Honestly you can't do anything. In American english, you can't do nothing!
Turn 3G off, when you don't need it. Keep brightness at as low as possible.
That's all. 4.1.2 drains juice faster than 4.1.1, it's the truth, doesn't really matter if someone agrees or not.
You could go back to 4.1.1 ROM you know and depend on your luck for that Exynos issue. Otherwise give up on great battery backup and stay with 4.1.2, like I'm doing. Nowadays I don't even monitor how much battery backup/screen on time I'm getting, on 4.1.1 it was the opposite story however.

Hey, so should I just resign myself to a gimped battery? What really hurts is how awesome the battery was before.
Any word on when samsung would release a good update?
Sent from my GT-N7100 using xda app-developers app

Download better battery stats to make sure there is no wake lock. I will advise despite my best efforts the battery life has plummeted when upgrading to 4.1.2. Stick to 4.1.1 for battery life. It still lasts much longer than an average handset saying that

After updating to 4.1.2 my battery runs down about 20% quicker overall I would say. 70% for your screen seems severe. Mine is always set to 50% auto and takes between 30 to 35% of the battery usage.

If you go back to 4.1.1.... Stock even....you'll have the same battery issue.

After about 2 weeks of having the 4.1.2 (the second update I received) on DBT my battery life one day just magically got better! I had been having terrible battery life (like 1 days worth) for 3 months, and now I get home every day from work with 50-70% battery. I charge it every night, regardless of the %. But it just magically got better. I'd say give it a go for a week or 2, and see if it helps. I don't know what happened with mine, but it looks like the software just "settled in" because I didn't install ANYTHING new, and in fact, I hadn't even uninstalled anything! It just got better after using it. Do a few battery pulls / restarts, too.

I went back to 4.1.2 last night and right now I'm at 50% charge, 17 hours standby time and 5 hours of screen time... I'd say my battery issue is fixed.. for now lol

I also must say that after a week or so of using 4.1.2 battery went much better overnight. I automatically turn on airplane mode during night, and on 4.1.1 I had like 1-2% drain overnight from full charge. After updrage to 4.1.2 it jumped to 10-20% !!! Now, it is down to like 4%, which is not that bad. Still have to see how it behaves during the day, I think it is not any better. Well, at least that standby drain is (much) better....

Anyone experiencing faster battery drain on 4.4.2?

I updated to 4.4.2 a few days ago and am noticing faster battery drain. Just curious if anyone else noticed this?

Yup. Have tried factory resetting twice. Clearing cache. Disabling nearly everything possible. No avail.

Mine was draining a bit faster than normal after the update. I let it run all the way down, and charged it up, and it has been fine since then.
Hope it works out for you guys.

Camera bug = Battery Drain
Did some looking around, and it appears to be a bug related to the camera (i know, sounds a little odd).
Here's one link of many I've found regarding this issue...Samsung has acknowledged an issue and is working on a fix:
"cultofandroid.com/53672/google-vows-fix-android-4-4-2s-camera-battery-drain-bug"

I am thinking this is more regarding the ASOP camera. We don't have that file or app that they say to look for.

I posted this in the 4.4.2 issues thread, but will post here:
EAS continuously running....I found this out as well after the update. I cant believe its low priority for such a major issue. I switched mine to manual just to be safe. I also found a major battery drain issue when surfing on the internet via LTE service.
Any way, I wanted to see if others could replicate my issue:
-Stock (non-rooted) S4 phone with the recent 4.4.2 update on LTE with 5 bars of service.
-I am using Chrome to surf the internet.
-I have Exchange and Gmail accounts. Gmail is set to PUSH and exchange is set to manual. (My hope is that having Exchange set to manual I avoid the EAS issue described above.)
-Majority of the boatware turned off
Scenario: While using Chrome to surf via LTE service I am literally able to see a 1% decrease in battery ever 2-3 minutes of surfing on the internet. Wifi is better, but still drains faster than 4.3.
Can anyone else try and replicate and respond back? I may have to do a hard reset to see if it will remedy the issue. :-/
Thanks,
Eric

What are you actually seeing for battery consumption?
I have google+ at the top of the list with >30% use. Definitely new after 4.4.2 update.
Seemed to be ok for a day and then popped back up. I'm going to try to see if it's caused by 1st use of the camera.

I'm not using live wallpapers.
Rebooting the phone and avoiding use of the camera did not help.
I uninstalled all google+ updates that that has worked so far, but definitely not a long term solution.

Well I would up flashing the MK2 revert, then changed my mind and re-updated to NB1 (these two processes involved many full-wipes and even flashing a .pit file). Installed all my apps one-by-one. I'm now getting better battery life. Still higher than previous usage by Android System (usually ends up being 14-17%).
NB1 now works pretty damn well for me. Once we get root I will be able to disable some stupid things like the boot sound and charger connection sound, along with a few apps that just don't need to be running like Knox and Security Policy Updates...

KitKat didn't kill battery life. Mine is about the same as it was before KitKat. In about 99.999% of the time an app is to blame. I have a simple but arduous method to find the app that's killing your battery.

I agree the battery has taken a hit. I used to ave about 9hrs of screen on time, now about 6hrs. I also have the chromecast issue. Strange thing is that sometimes the screen doesnt even show up In the battery stats. Sometimes the usage time doesnt change when it shows in battery stats. I am stock, 32gb white US model updated with Kies. I have done many factory resets. I have tried it for 2 days without installing any apps or disabling any samsung bloat, with no change in the tablest behavior.

Kitkat sent my note into fits. Battery life was terribly erratic at first. Dropping 30% in an hour, then suddenly jumping back up by 10%.
I tried factory reset.... nothing changed. Then I used the Battery Callibration app from playstore. Ran it and followed instructions exactly. (Waited til it was charged 100%, then run the program, then completely drain battery, then let it charge continuously back up to 100%).
Go figure............ since then things have calmed down and I am getting the same battery life as on my old Jellybeans note. (I know, because I've got two of these tablets and literally compared them side by side.)
Or, it could also be that after firmware upgrade things need a bit of time to settle down. Hope this helps.

Mine settled down after about 3 days and several resets. Now the battery seems comparable to pre-KitKat.

I don't think it is kit Kat. I'm running kit Kat and easily see 9 hours of screen on. It is most likely an app you have installed that is doing it.

Then not everyone would then mention that it is not change or improved (in stand-by).
No, normally a app or bad file on the sd-card is killing here the battery. All tools to find this out, are already mentioned here. Good luck.

4.4 in and of itself isn't causing poorer battery life. In fact, owners of other devices are reporting improvements. The Exynos N3 for example. There aren't any battery life issue threads on the Pro forums and they have the same h/w and we're most likely using their 4.4 drivers and kernel. There are threads like this in every device forum when an Android version upgrade is released. It's almost always due to a bad flash or a rogue app or service. That and older apps that haven't been updated in ions and aren't playing well with the new OS. People here have reported shorter charging time and longer battery life. So what's being discussed isn't universal. I'd suggest doing a stock recovery and reviewing older apps and those that aren't developed by known and larger developers.

I have a Shield and S4 too. For every poster raving, there seems an opposite view on battery life and the SD card issue.
The SD issue makes battery life debates moot. Google has an Apple wannabe syndrome. Perhaps they will rebrand as Goople.

You can recalibrate the battery by running it down below 20% then recharging. I have seen it recommended to do this every 30 days or so.
My Note 3 with KitKat started using 20-30% of the battery at night while it was idle. Looked and looked and couldn't find a clue to the problem. Decided to reboot, the next night it was fine, used maybe 2-3%

I am overage to believe in this new-world mysteries... and I am still hoping that nobody believe in this stories. Please, let me not became an old, lonely infidel.

Nope
The update did not kill my battery. Did you come from a rom?

Agree and disagree!
I did have charging problem and battery drain right after KK update. I have to do the Factory Data Reset. Luckily my tablet is back to normal if not better. I did spend sometime go thru all setting. So I managed to get 4 hrs of screen time with moderate use and I still have about 59% of battery.
So I say kk is good or better then jellybean

Everybody wants to be a comedian.

I don't have this issue but maybe affected people should read this : http://forum.xda-developers.com/showpost.php?p=52366635&postcount=236

I updated a couple days ago and since then my battery just sucks. It just went from 100% to 29% in 2 hours just using Youtube. It can't be right. Definitely it's the upgrade!!
I loved my Note 10.1 2014 out the box that I decided not to root. So it's factory stock and suck very bad.
If it's a bad app I can find it. It worked flawlessly before the upgrade.

Factory reset and see if it still happens. A dirty flash can do weird stuff...

Yeah, im not getting great battery life either since this update. I just reset the tablet in the hope of tracking down what's the issue.
Troubling, since battery life was so great previously.
