Battery Problem

Hi. I have a Voda branded TP2.
I have installed the 1% battery indicator and have realised that the battery is dropping at an alarming rate. In two hours without any data activity, just two calls of 5 mins each and the battery has already reached 74%. The number drops in front of my eyes. Quite scary actually.
Anybody else faced a similar porblem?

2 things I can advice you (as a TP2 beginner)
-First times: charge up to 12 hours non-stop even when light is green (has nothing to do with phone but with the chemical proces inyour battery) this will prolong lifetime
-This TP2 WWE ROM has a lot (and I mean A LOT!) of background running stuff compared to other WM 6.1 - ROMS. So you thing it is not using any current but it is!
Maybe you could install advance task manager and check out all running programs and processes ...
hope this helps ...

Thanks. I have done the 12 hours charging many times - about 6-7 times. Will try the advanced task manager.
Anybody else with a battery problem?
Any application / software is known to be a battery drainer?
Thanks

Had a strange one last night. Went to be, put the phone on charge (was about 16% iirc), and the orange light came on to say it was charging. Then, this morning at about 3am, I hear the phone making bleeps. Check it out, and it's at 5%, with orange light flashing. Take out charger, put it back in, and it starts charging. I went out afterwards, came back about 4.30, and it says it was about 80% complete. Go sleep, wake up about 7.30am, and it's fully charged (green light). Then, I unplug charger, turn on, and it says 96%, and I notice it dropping the amount of charge in front of me (like OP's notice), until it got to about 91%.
Now, about 5 hours later, it reckons the charge is 74%. So dunno why it went down so quickly, and why it didn't actually charge... But will keep my eye on it and see how it goes...

data connection
Another way 2 keep your eye on it: check data connection (start>settings>connections>comm manager) a lot of stuff open this connection which uses power. if it turns on without you knowing .... (especially auto-update plugins (weather?)), sometimes AS also ...

that it isn't a good idea to do "old style battery cycling"
I really don't know what to think of LiPo battery management, so many different theories.
Also, something that annoys me is that I fully charge the TP2 overnight, in the morning the lights green. If I simply unlug charger and plug in back in it well go back orange and stay orange for a good half hour... and I can start again a few times...

To be honest, I had to hard reset my device couple of times and haven't had time to 'fully' recharge it after the resets.
I guess I will give it a few days of full charging and then check on the battery.
But, I am not joking when the 1% battery meter just drops numbers faster than a meter at the gas station.

I had this problem when I have push mail turn on. If you disable push mail and set it to receive like every 15 mins, it save the power a lot.
Try the advance config to auto disconnect every x mins, this will helps as well.

Hi HaveryR and others,
yep your source isn't to bad. Beginning with full charges (6 to 12 hrs instead of 3 like the manual says) isn't about the old charge-memory story (because Lithium-Ion battery don't work this way, only the nickel-cadmium and nimH do) but about fully charging cells.
I mean the best way to look upon this is like a pile of bricks on top of each other (all different cells if you wish). So the first time it is important to give all the bricks enough time to charge - so even when it says 100% it does not mean that it has (you're indicator is a feedback of a reading by your cpu). So not all the bricks (let's say) have the same quality (yesyes even in this day and age of hight teck).
So you can also take this parallel to discharging: if you discharge fully, you risk that one of these bricks get busted and so will NEVER recover.
So i agree on this with your source a LiOn batter is bettery served with frequent partial charging and must NEVER be drained completely

Guys,
I put the TP2 on for charging the whole night (about 9 hours). In the morning the LED was green and the battery meter said 100%. I took the charger off from the handset and re-inserted the tip in. Guess what? 95%.
AM not sure if it is a battery problem or handset problem?
Its come down to 73% with just one phone call of 5 mins. Mail is on, but its on manual and havent pulled anything since morning.
Any idea?

Is my phone the culprit?

So like everyone else my battery life sucks. No big deal. I bought the extended battery from Sprint, and I can see the battery diminish in front of my eyes. I mean dropping 1 percent per minute. Is there a way to test the phone to see if it is the culprit?
Sent from my PC36100

ther are lots of ways to check things. does it drop 1% a minute all the time meaning you only get 100 minutes? does it only do it when you take it off the charger at 100% where ti will drop to any where from 99-90% in a matter of minutes?
if the later then thats normal and is because the phone doesnt have a trickle charge. this means that the phone charges your battery to 100% then stops however the indicator on the phone will not change it will still show 100% once the acctual power reaches 90% the phone then charges again up to 100%. what this means is once you take your phone off the pwoer if it has been sitting there even if it says it is at 1005 it can be any where from 90-100% which the battery quickly changes to over first few minutes.
If it happens past 90% and all the time then something is wrong and you likely have at least 1 if not more apps running wild on you, you have things set to sync constantly, and you have everything under the sun turned on for your phone.
for apps the paid version of system panel is very nice for monitoring you can go to monitor top and top apps and see which apps are using the most battery/cpu.
witht he information you have given that is aobut the best i can tell you. I would not say everyone has crappy battery life with the evo as i have slowly gotten my phone set up and now with moderate usage i can get 14-15 hours and at least 8-10 with very heavy usage(stock battery) which i dont consider to be crappy battery life.

I appreciate the response, and I forgot to add that I'm running stock unrooted sense. This is not my first Android phone so I know about battery managing. I don't have everything sync every two minutes nor do I have everything turned on. It does drop rather quick even past 90 percent. I think it might be the phone it self. I doubt I got 2 bad batteries, one being extended. I'll see if I could get a device swapped out.

My first EVO was like that. It drained quickly shortly after charging. I could never figure it out. Till one night before going to bed, I noticed something weird about the bottom keys on the phone. They were " very dimmly " lit. The home, menu, return, search were all dimmly lit. It was I believe a defect in the phone. I got it swapped out. No problems like the 1% drain since then.

my 1st GSIII was defective(phone HOT while off)

Just an FYI,
My 1st sprint GSIII was fine for the 1st month. I could get upto 3 1/2 days of battery with very light usage (mostly standby time). NOt sure what caused what happened next but the phone became extremely warm and the battery life dropped to approx. 2 hours. The phone was very warm even while off for hours!! And it obviously got even hotter while on the charger. The only way to get the phone to return to room temp was to pull the battery and leave it out for a few hours. Turning wifi/data/sync/GPS etc. off did nothing. The odd thing was, the battery was a normal temp. The heat came from the lower part of the phone (where the processor is). It also gave incorrect battery readings. While plugged in it would read "100%" and "charging" the LED stayed red, never turning green. I also could pull the battery and put it right back in and it would read 20-30 % difference VS. when I took it out.
The phone was swapped at a sprint store covered by insurance.
The only thing i did differently usage wise was link the phone to my dropbox account. It seemed to sync normally so i can't confirm dropbox caused the issue. I just can't figure out what the phone was "doing" while it was off. Just thought i'd share the story with the phone. The new 1 is running fine.

I found this today. Appears to be helpful with heating up and improved battery life.

This doesn't sound good at all. My cousin's GII on AT&T did something similar to this. The phone would be completely turned off and it would vibrate every 10 minutes. Even pulling out the battery and reinstering it made it automatically turn back on and vibrate again and again.
Hopefully this is an isolated issue what you are talking about.

What kind of signal are you getting?
Mine was like what you descrbed for a couple days(almost no signal at home) and I was getting ready to return it but didnt have time because I was leaving for Vegas. Long story short when I got to Vegas I upated profile and PRL and havent had a problem since. Maybe the towers in your area are under constrction.

My phone has gotten hot ever since I got it, but it will cool down when I stop using it. I am getting horrible battery life even witha 4300 mah battery. today it wouldnt even last 11 hours. It had 3 hours total usage time on it. I am now trying another 4300 mah battery to see if that is the problem or if its the phone. my reg battery wont last me very long either. I am also using juice defender free version and advanced task killer plus the built in task killer and I cannot get my phone to last very long. With my orig Evo I had the sprint extended battery (2500? mah) and it last me til bedtime with 50% left.

The only time this happened to me was when an badly behaving app "ran away". I would get really bad battery usage at the same time. I could cure it by clearing ram, which shut down all the running apps. Since this hasn't happened to me in a while I'm guessing that whatever app was doing that to my phone has been updated to fix the bug.

My issue was very odd. My phone was normal lasting up to 3 days with very light usage. It would sit for hours at "room temp"..the only thing i did differently was link it to my dropbox accnt. It seemed to sync ok..it was shortly after that i noticed the phone was very warm towards the lower 1/3 of the phone. I thought maybe there was something running or taxing the processor. So after working on it for a few days(turning everything off i.e. wifi/gps/data/sync/etc etc.) the battery got worse and worse. I then unlinked dropbox, stopped all running apps and let the phone sit in airplane mode over night. Still no joy. So i turned the phone off and let it sit for about 6 hours. It was still "very warm" while off!! At that point I pulled the battery for about 2 hours and the phone returned to normal temp. What could the phone be doing while turned off for hours?
The phone was stock and updated. I use an airrave so i dont have signal issues. The processor seemed to be running at full load even while the phone was off. The battery life went from around 3 days to not even 2 hours. The phone did seem to have the known "cell standby" issue(where the counter is reporting an incorrect usage %). While charging, the phone was even hotter to the point of me thinking it would burst. Oddly enough, the battery was at a normal temp. It was no where near the temp of the bottom of the phone(where the processor is located).The new GS3 is running normally so far. The tech at the sprint store couldnt figure the old 1 out so they just replaced it(insurance/no charge).

Annoying Battery Issue

My Note 4 is 14mo old and for the last couple months it just shuts off on me even though I have plenty of power left.
I am a light user and usually have enough power for all day use. I rarely use my phone down past 10-15%. I always put my phone on the charger when I go to bed at night when I have somewhere around 20% charge left. If I notice that I might not have enough power to get me through the day I'll put it on the charger somewhere between 30 and 40%.
Lately, like tonight I got a low battery warning at 30% power while I was on the phone. Not even two minutes later it shuts off. When I turn it back on it starts to boot up but then shuts off again. When I put it on the charger it was completely dead. This only happens 3 or 4 times a month but it's annoying because often it happens at the most inconvenient time.
I've also had it shut off and then when I put it on the charger it starts charging at 28% power.
Please let me know what may be going on here and a solution...
Thanks...

I had the exact same issue. I had 2 different batteries shutting off at 20-30%!.... Replacing the battery to a brand new one simply fixed it!.... if you are going to order one online try to avoid unknown brands . Also, pay attention there are some fake Samsung batteries claiming to be authentic.
Also if you still have warranty, contact Samsung and they should send you a new one. That's what i also did.

So you think its the battery and not software related? I was thinking software issue because I don't abuse my battery by running it dead and it's an intermittent problem.
I know that the life cycle of Li-ion is greatly reduced by repeated draining to below 10% (my kid's phones suffer from that. Seems like they can't make a battery last more than 6mo) but I've never had a phone battery go bad on any of MY phones including my old Note 2 even after two years. Maybe I just have a bad battery?

Doesn't matter whether you abuse the battery or not. Some batteries just go bad faster than others. I also think it's your battery.
A factory reset without restoring apps will rule out a software issue though, but since we can't root, it likely isn't anything messing with your battery percent unless it's just an app draining your battery. But even if it were the latter, your battery wouldn't die then start charging at 28%.

Pretty sure this is an actual built in feature. Mines always died at ~20% (since the 5.1.1 update) and once plugged into a charger and rebooted all my running apps and clipboard info is still running as if the phone never died.
My battery is brand new (from warranty replacement) and it still does this so this is why I think it's a "feature" to keep you from losing data in the event of a low battery event. Just my opinion.

It's not a feature. Mine goes all the way to 0% before it dies. I once read to take out the battery, hold the power button for 30 seconds (while the battery is out), then put it back in and see if it helps. This supposedly gets rid of any residual power storage. I don't know if this is a placebo affect by after I did that, my battery now goes all the way to 0 before dieing.

Not exactly a placebo, but not sure if it truly helps. Doing this would clear all electricity stored in any capacitors in the phone. I'm just not sure how this helps.
And my battery goes all the way down to 0% too. It's not normal for the phone to due at any other % (except maybe 1%).

Battery charge issue...

Phone was at 98% battery. Did a reboot as I do every morning, and when it started up again it showed 91% battery. I know reboots don't take 7% battery, so what gives?

My Pixel 2 XL has been having some battery reporting issues, I noticed that when I took my phone off the charger it would lose 15% very quickly then stabilize. Rebooting would also cause a drop in indicated battery %. That's my guess. Investigating to see if it can be fixed by doing a full charge/discharge cycle.

I've also been seeing this issue! I will also be letting it do a full cycle today to see if it helps since it only started a few days ago.

My battery seems to be okay but my charge port when I place the cable in it doesn't feel like it fits snugly it almost has a slight wobble to it. Have you guys been noticing that as well?

I've actually been experiencing this as well for a week, I called up Verizon and they shipped me a new phone. So far no charge issue anymore on this one.

I have experienced this too

Tested this again this morning. Had the phone charging overnight.
Unplugged it, it showed 100% battery.
Immediately rebooted, and it dropped to 96%.

With a lot of phones, battery stats reset on reboot. Also- the percentage isn't a perfect science. Just let the phone do its thing. Run the battery down and recharge it. No need to reboot the thing every day.
The battery has been great for me. I use my phone extensively throughout the day, maybe 3-5 hours on time, I always make a day of use without needing to plug in. I had a light use day yesterday, and had 30% left @ 11pm, after pulling off charge the night before @ 11:30pm.

Pleased to announce that (in my case at least) doing a full cycle reset the fuel gauge and it is now working properly. I've never seen a device come with a miscalibrated fuel gauge from the factory, so that was odd. I usually keep my li-ion powered devices between 80% and 30% SoC(state of charge) to reduce cell degradation so we'll see if the fuel gauge becomes uncalibrated over time (which would be somewhat unusual) or if this was simply a software fluke.

Yea I have noticed that in my case, my phone says 100% on the charger so I will restart the phone while still plugged up and once it's booted back up it says 98% so it lost 2% while hooked up to the charger lol. Doesn't seem to affect the battery life. I'm still able to get 5 hrs of screen on time but I will try to kill it completely and charge fully today and see if it fixes it.
This morning I didn't do the restart and didn't use the phone or even turn my screen on and within fifteen minutes I turned it on to 98 % remaining.
