So, this post is 1/2 "rant" and 1/2 "any ideas", but the JI6 Update has been (in my opinion) a very serious letdown.
First of all, I can't be alone in thinking that the late-September update from Samsung would be a full-blown upgrade to Froyo. Obviously it's not. I guess we'll wait awhile before that's released
Secondly, I'm one of those sorry saps that had the update soft-brick my phone. It took me a few days to get around to the ODIN fix (bumping me back to "stock"), but it was still a royal pain.
Thirdly, I've already seen some issues that I didn't have before. For instance, the phone "froze" on me while sitting at home: no screen response. I had to pull the battery and power up again. Nice!
Finally, the battery life is utterly horrible for me -- and I'm not sure why. Currently at 26% battery life (now 8h 4m since unplugged). 34% of the usage is "display", which has been on for 28m total. 22% is cell standby. 15% is phone idle. 10% is voice calls (2m 10s of that). 8% is the Android System. So on and so forth. Basically, I've *hardly* used my phone today, yet the battery isn't going to last thru to the afternoon. I have 6 active applications, with none of them hitting the CPU at all currently. Best of all? The battery icon looks like I'm about 1/2 full, so evidently Samsung couldn't be bothered to make that icon accurate. I know about the battery icon mods out there (I've used 'em), but I figured Samsung would take care of that.
Sorry for the venting, folks. Is anyone else seeing similar stuff? Any ideas on the lame battery life??
Thanks,
Yip
For me Android 2.1 which samsung released in Galaxy S is exactly like Windows Vista ! No matter how many updates you release for it still will make your phone **** !
The only option is to release a full new OS which is Windows 7 = Froyo !
Better than Windows NT = 1.6
Getting your phone bricked isnt the updates fault, there are hundreds of threads out there and reading just one couldve given you signs of warning.
As for your battery life, I am willing to bet your phone screen is full of widgets. Try limiting those, as well as automated syncing. I get excellent battery life that can EASILY last me the whole day (I actually find myself running avatar/pandora at the end of the night just to drain it so I can recharge the battery).
However, I do agree that the inaccurate battery reading should have been fixed a long time ago (or at least in this update) and that froyo should have been included with the release of this phone.
Your cell standy is too high which means you have things constantly using the cell signal to pull data, thus draining your battery. Right now I'm at 72% with 67% display, 14% voice calls, and 9% cell standby. Been unplugged for 3 and a half hours.
Not great but I'm purposely trying to let it die because I'm reconditioning.

Ha! You may just be right on that. Eclair seems like a fairly lame version of Android, if you ask me. Not horrible, but not great.

"Signs of warning" means nothing, my friend. There are folks who didn't even *root* that got soft-bricked with this update. It was (somehow) poorly handled.
As for your widgets comment, well... you would've lost the bet. I use a single screen, no widgets, no weather stuff, bluetooth off, wifi on (but currently turned off), and nothing extraneous. I run Android about as light & frothy as you can get! I prefer speed over just about everything.
Any other thoughts, though? Perhaps I should re-load Autostarts to see if there's anything strange launching at boot time...

Interesting. Any ideas what would be pinging the cell standby so much? I'm in a high-bandwidth area (full bars), so it's not like the phone is struggling to get signal. I use Gmail and Exchange, but my Exchange sync is set to "hourly", rather than push.
Doesn't seem like I'd need to disable my 3G connectivity. I certainly have never had to before.
You should probably reflash the update. JI6 was great on my phone, no hiccups, no lag, perfect GPS.
Also, you should recalibrate your battery after the update and give it a few days to settle down. I always get horrible battery life after flashing a rom, but after a few cycles I'm back up to 24h+.

Honestly, I wouldn't know unless I knew your full setup. What I will say is that I do have a lot of widgets and apps running that pull from the internet but yet my cell standby isn't as high as yours. I haven't reduced any of my sync intervals either. The 3G radio can really drain battery fast, faster than even the screen so that is a problem.
Also, in JI6, they increased the strength of the radio so it drains even more battery. I am running the JI6 modem however.
You should use something like WatchDog to see what is constantly running and using CPU. That could give you an indicator of problem apps.
Well, I'm disabling some startup items: Visual Voicemail, Telenav, and Daily Briefing -- none of which I use. Maybe that'll help. I don't know...
I was really trying to run "stock" this time around -- not so much fooling and tinkering with things, but it doesn't appear to be paying off for me. Frustrating.

Oh wow, yea definitely you need to disable all of those. That's the first thing I do. I actually uninstall Visual Voicemail, Telenav, Amazon MP3 etc. ALL of those things constantly run for some reason even without you opening them once.
You're not alone. My battery life is terrible as well after the update. I'm losing 4% an hour on standby.
That said, my phone is smooth and working great when I do use it.

Again, if you didn't do so after the update, wipe battery stats and then do a few full drain/charge cycles. My battery life always sucks after flashing a new ROM, but it always goes back to normal given time.

after the update for me, my gps is much better, but i actually have more lag then i had stock before....
so I need to either flash a kernel, lag fix, or a rom with at least one of those.... its kind of frustrating to have lag just from opening or closing a simple app, messages, or call... I honestly cant believe a phone with these hardware specs can have lag just from somthing as simple going into the dialer and exiting out...
Battery life seems to have decreased a little but still getting a good 20+ hours. GPS is a little better with use wireless networks. Lag is an issue now though. Didn't have much before a the update. Hopefully its solved in another update or froyo.

So I applied the update on Tuesday through Mini Kies. First experience with this update, it's been great. My phone seems to faster, really I hardly experience any kind of lag or slowdown (and this is in comparison with my stock vibrant running OCLF). Battery life even seems to be better, but that is probably to do with conditioning. So everything has been good except for the fact that my phone has froze on me TWICE today. I'm thinking it's something to do with the apps though. I was in Layar and it was working for a bit when suddenly, it froze, I didn't have to pull the battery I just held the power button down for a good 5-10 seconds and it restarted. The other time was in a game, which kind of concerns me. I suppose I can reinstall both and see how that goes. I'm thinking it has more to do with the apps possibly being corrupted. The first thing I did was install the 2.2 market on my phone and I ran the update all function on like 15 apps that needed updating. Not a good idea imo, the market went crazy and forced closed a couple of times. I'm not entirely sure what is going but it seems like my phone is only freezing in certain apps. I hope it's not just some random freeze that can happen at anytime, that wouldn't be no good.
You guys complaining about battery life... i would Love to have your times. I got 3 hours and 8 minutes today on a fully charged battery.
Has anyone solved the "Low battery" and "immediate turn off" problem yet?
Man this is the most frustrating issue EVER.
I'm running SRF 1.1.0
I have a 3500 mAh battery.
For some Farking reason, if the battery is under 50% and I get a call. It will RANDOMLY beep LOW BATTERY and turn off, in the middle of the farking call!!!
You turn it back on and it'll have 40+ % charge left!!!
AHHHHH!!!!!
After watching the 25 how to videos, I fixed almost everything that pissed me off, but this one thing drives me bonkers!!!!
I think that's the battery. Is its a yoo-bao from china (cheapie) or a good brand from a reputable source(sedio)? I have that problem with all the cheapies I bought on ebay.

It's not just the battery. My stock phone and rom does it too when the battery gets to 15%. When it reboots it has 20 or 30%.
This phone should never have been released with such a serious bug.

For "such a serious bug" it doesn't seem like many of us have it... I can keep a call all the way to 0%...did it a few minutes ago. Have you tried calibrating the battery stats?

it's a cheapy battery.
However, it's also a bug somewhere in some software...
If it hits 15% when u are NOT on a call, the phone doesn't shut off. It's only when you're actually talking that it does it.
I'm surprised to hear STOCK people saying it happens to them... When I had my phone stock it didn't do this. I assumed it was a ROM issue.
I would try calibrating... I believe there's an actual app in the market to do everything for you. I'm fairly certain its free, so ill post a link, but if its not, I apologize, and well get a mod to take it out.

Yes. I've calibrated my battery. I have seen a couple threads on the issue. I have repeated the issue on several roms and modems. Happens every time i'm on a call and the battery gets to 15%. That makes it serious since it is a phone after all. What if I was talking to 911?

What I'm hoping for is I can figure out what you guys are running that doesn't crash on you when the low battery beep happens.
I think this is a battery issue. I never had this problem with stock battery and it happened twice on cheap 3000 ma battery I bought. Returned the battery and got another one (same kind) and this one works fine. I think this is a manufacturing problem with cheap batteries. When you look at reviews of more expensive ones online, you never see anything about this problem.
I have found the solution! It turns out that our phones, much like a simple light bulb, just don't function when they don't have enough juice...
Since I can't modify a light bulb to magically require less power, the only solution I have found is to provide the specified power level. I have applied this same method to my phone - when the battery gets close to that magic threshold, all I do is - get ready for this - charge the phone again!
Seriously, though - everything takes power to operate, and a low battery can't put out the same current and voltage as a fully- or even half-charged battery. This isn't a bug, it's just a fact of life (with current technology, anyway). Who here complains when their almost-dead AA batteries can't power an Xbox 360 controller? Most of us just replace them with fresh ones (or charge them) and keep going.

This! Cheap batteries are never worth the money. I bought some cheap chinese rechargeable packs for my 360 controllers... they ALWAYS show low charge even if I just charged to full. Same deal with cheap chinese cell phone batteries.
I am sure the battery calibration is way off with one of the cheapies.

Ok Mr. Smarty pants. You are not understanding the problem. It happens with the stock battery too.
The SECOND you hit 15% while on the phone and get the battery low warning, the phone turns off, MID CALL. You turn the phone back on and it will last hours, even on the stock battery.
If it hits 15% without being on a call, it does not shut down.
That is the real problem here.
This has happened to me once , what could be the cause ? Defective phone or software?

You mean just like a 360 controller can have enough juice to turn on, but not enough to actually play? Or how a flashlight will be too dim to be worth it when the batteries get low?
Would it be better if the battery ran like a champ right up to the second that it shuts off without warning? That would fix your problem - no notification when the battery is low (the sudden shut off can't be avoided until we find an unlimited energy source small enough to fit in our phones)
Your expectations are unrealistic. Just sayin'...
Sent from my SPH-D700 using XDA App
J3ff, it's likely the cheap battery. Here's why:
Charge level is a simple linear voltage function. Our phones consider 4.2V to be full charge (100%), and empty to be around 3.6V (0%). The voltage drops roughly linearly between these two values as charge is consumed.
The kicker is this: The voltage seen at the battery terminals is also affected by the interaction between the internal resistance of the battery and the instantaneous load, or current draw. For electronics buffs, this is the classic V=IR, and what happens is that the voltage on the battery will drop by IR in addition to it's unloaded voltage level due to whatever the stored charge state is.
Good quality batteries have a very low internal resistance, and will not drop much voltage due to an increased load. Crappy batteries are just the opposite, and even though they do carry the charge storage (most of the time) advertised, they are only suitable for low load applications.
What's happening is you have a battery with a horribly high internal R. When you make a phone call, the load increases A LOT -- transmit power goes way up. This if why phones get hot when talking on them -- they really suck the juice.
As a consequence, because of the high resistance, voltage from the battery takes a nosedive. At an "idle" reading of 50% (3.9V, thereabouts) you're probably dropping more than 0.3V when the load goes up during a call, the phone panics, and shuts down to protect the battery (LiIon doesn't like to be discharged below 3.3V, and can be damaged).
When you reboot, the high load is gone, so the voltage shows higher again, reflecting the fact that there is truly still plenty of charge stored and available. The battery simply can't handle gulps, but only slow sipping.
High internal R is one of the most common reject reasons from mfgs, and those batts are sold on the cheap to dealers and distributors in a secondary market. Honest ones then resell into appropriate application spaces where low-current is all that is needed. Most, however, are not that scrupulous, and sell right back to the same market, leaving behind puzzled and unhappy customers.

Okay so I posted here a week or so ago about how my Xperia Play was epicly failing....it was force closing everything and dying in just hours.
So I factory reset and used Titanium to restore all of my apps and stuff...and so far the crawling speed/force closing has for the most part abated (opening up texts and contacts still sometimes takes forever or force closes)
but the battery issue remains. My battery is absolute garbage at the moment. It drains by 10 percent per half hour if being used or even more!! And it gets hot constantly, and obviously at that time it really sheds the power and dies quickly.
If I'm CHARGING the phone WHILE using it heavily, it WON'T power ABOVE the % it started at!! It stays constant or goes down!!
I'm not sure what to do. Should I let the phone die, keep it off, and charge it while off till its 100%?
Or maybe my phone is approaching the situation it was a week ago...I constantly check the running apps and its the usual suspects, nothing crazy. I had to delete official facebook app because it almost ALWAYS lagged and oftentimes force closed.
It says cell standby is using 40%, wi-fi using about 22%, voice calls 17%, phone idle 15%, and dialer 14%
What happened to my phone? Why is it such a clusterf*ck lately? Any ideas/advice?
Are you leaving wifi on because that will really suck the battery down? Also do you live in an area with bad signal? Put it in airplane mode and see if the battery still discharges as fast.

My r800x dies in 6 hours whether it's on airplane mode or not. I've re calibrated the battery like 5 times so far, and it just won't get better. I'm regretting moving to verizon to this. I should just get a sim card and go back to my HTC Inspire. I can leave the r800x in idle with the screen off, while in airplane mode and it will still die in 6 hours. It doesn't even last a whole day of work. Mine's also rooted. I need some serious help with this phone.
Turn off wifi.
If you have it on it will search for wifi networks all of the time (unless you're home and connected to your own wifi) and it will suck your battery dry.
I don't even use wifi. I don't have access to the router at home, and my data is turned off when I'm not using it.
Perhaps you have a bad battery? Maybe replacing that will solve the issue.
It could be. Every time I try to check my battery's health, no matter what app I use, or even if I do it from the service menu it reads at "unknown". One app says that my phone doesn't even have a battery stat service, or something along those lines. I was considering just buying one of those mugen batteries for my phone, considering that I brought the issue to verizon's attention, and they told me they were gonna send me a replacement battery, but I never got it. This was all about 2 months ago though.
wow, sounds bad. mine will last all day, its an r800x on 2.3.3 as well but i can use it like normal, play about a hour of games on it, talk on it a lot, use wifi and 3g and do some average surfing and it will last at least 24-30 hours...
i'm thinking it must be a bad battery as well
Im running 2.3.3 verizon from the FTF and my r800x would last almost 3days, and thats with texting/talking/surfing using 3g and playing a shyt load of sonic . I would replace the battery with a genuine Sony replacement, dont ever buy a ebay knock off ! Furthermore, I don't believe apps that check your battery health are accurate at all, so dont waste your time.
Best way to check (imo) - Before you charge it up, let it go to 0% and die. Boot recovery and wipe the battery stats, turn the phone on and charge to full. After its fully charged, let it sit 10-15 mins on charge. Then pull of the charge and use normally, if it still dies fast, replace the battery.
If this idea was already posted sorry for double post

I swapped mine out for similar issues. The replacement doesn't have the same issues yet but I haven't put a single app on it. I can't say that adding apps caused it before because I remember it similarly not getting anywhere when charging while using. I also experienced it dropping while charging but it turned out to be a that the MTP device wasn't starting on the PC so it showed as plugged in and charging even though it wasn't (check the Device Manager). My Alienware M11x actually supports charging devices off that particular USB port when it is turned off so it was a bit hard to figure out when it seemed to charge some times and not others.
So I got a new battery. Battery life oz still terrible, phone still can't detect battery health.
Not sure why, but my battery voltages are higher than 3.6 :/

Hate to tell you but it sounds like your Play is defective.
The only way it would always get hot like that is if it was always running, that would be mainly driven by being in a REALLY bad service area that its always searching. I have a boatload of games etc on mine and my battery life varies from 2 days to 3/4 of a day depending where I am. Heck my battery life varies as to whether I leave my phone on my desk at work or on the shelf above me (lasts longer on the shelf).
But the fact you said that even in airplane mode it eats the battery, and a new battery didn't do the trick. I would say you got a bad one. Still under warranty I hope?
i'm not entirely sure. I got mine through verizon in august or september of this year. Not sure if Verizon would handle replacing it, since I didn't buy their extended warranty. I read somewhere that SE themselves can handle it since it's not a year old yet, but my phone is kinda required for work.
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,

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!

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.

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:

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!

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.

I have samsung galaxy s2 just over a month or so and i have big problems, due to battery. I know this is common issue on this device.
Until now i try to recalibrate battery like that, no hard reset. The phone it;s new and it had ICS 4.04 installed on the first place.
1) drain all of your battery untill phone shuts down
2) turn on and drain battery until phone shuts down ( repeat until you are unable to turn the phone on- this step is very important because we need to drain the battery competely)
3) take the battery out and wait 5 seconds or so and put it back in
4) Charge the battery while the phone is off
5) when the charge is 100%, take the charger off then charge again to get 100% again
6) turn on your phone and enjoy your new battery
Once i try to take the battery out after charge, and wait over 2 minutes. I know this is a common issue of s2, but i have some screens, maby someone had similar problem.

Next, i'll try Battery Calibration (can't post the link, new user) tool from the market / wait for Jelly Bean official update. Then hard reset. Next step: service.
The screens
Time to get a new battery !

But it's a new phone, new battery (
great
The batteries in these phones can't be calibrated per se. Just use it normally for a bit. The peaks and troughs in your battery graph are because you're clearing the fuel gauge data. Mine would drop from the 73% I'm on now, to about 14% if I cleared the fuel gauge chip data, until it relearnt its settings. Just charge normally and use it for a few days, it will sort itself out.
If not, new battery.

Im having the same problem. Tried swapping batteries with another S2, recalibrating the battery and even installed another rom, same problem persists. The phone will auto switch off after a few hours of not using (overnight especially), and batter will drain like mad when it happens. Brought the phone back to samsung for repair now.
Same here...

I'm currently having the same (really annoying) problem. My international GS2 is less than a month old and uses the latest official firmware on ICS. It happens almost daily -- or should I say nightly? The phone has at least 60-70% of battery left by the time a go to sleep. When I wake up in the morning, it's completely depleted. My stats look exactly as in the screen-shots in the first post. I'm always charging/using it "normally" but it hasn't sorted itself out.
I don't really know how to solve this and it's frustrating. The Internet has mixed "feelings" about the solution(s)... However, same as with my battery issue, I'm looking for something more stable and reliable.
Am I missing something? Does anyone know the exact cause and how to fix it?
Hello, I took the phone to a local service (pointed by Samsung from my country) and they replaced my motherboard and another pice of hardware....something in the recharging sistem, i dont know details. I think there is a "lot' of bad motherboards... people form the service call it a generic name.
In conclusion, the problem was the motherboard, not battery. I have recovered the device from service one day ago, if i'll experience any problems... i'll get back with details.
Cheers
