Battery Life / Recharge Time?

I recharged my phone in an hour when it had just powered off by itself for being too low... I used it for like 5 minutes and it was already down to 80%... Bad battery?

Sure sounds like a bad battery.
Just to make sure...
1) make sure you don't have some app that is running GPS
2) If not needed, try turning off BlueTooth
Those two items will drain battery faster than usual.

I sometimes find the battery is really inaccurate, depends on if the phone's running hot or whatnot...
Also you might want to get a task manager and periodically close all the apps (some apps have a one-click kill all widget), and turn off syncing, gps, and bluetooth

Battery indicator hasn't always been accurate or me - even with a brand new battery

There are several apps/widgets that are poorly coded which cause high battery drain as well.
Try only using stock widgets as well, I find that helps alot.

Yea, the only Widget I run thats not stock is Beautiful Widgets Home Small, set to update every 2 hours.
I have bluetooth and GPS off always unless I'm actively using them. I just seemed strange it was so fast to recharge mainly.
I've noticed the battery capacity jumps up and down depending on what you are doing. For example if I disable 3G, it jumps up, if I enable it, it might jump down 10% briefly then go back to where it was...
Very strange.

Also, I find the app Juice Defender (free version) is a life saver. My battery life has gone from around 12 hours to > 2 days since using it.
What it does is disable your 3G AP and only enables it every X minutes for Y minutes.. I think the default is 15/2. The result is you still get your notifications (a few mins behind), but your battery lasts WAAAYYYY longer.

Thanks for the tip!
Now going hunting for "Juice Defender".

yeah, juice defender is great. The free version has limited options but the default options really save battery life on my vogue.
I read a while ago that there was a problem with the stock text messaging app. Is that resolved? I use Handcent SMS, but i don't know if it is good or bad for battery life comparatively.

JuiceDefender is fantastic, it works. Except you can't be listening to anything and have it running (music, podcasts, etc...) because when it kills the 3G connection the audio stops. I've talked with dzo and looked at the code myself and I don't see a way to keep it from happening unless there's a way to kill the 3G connection without issuing an 'ATH' to the modem or somehow ignoring the 'No Carrier' message that follows it...

this happens no matter what music player you are using? I was hoping it was just Cube, but had not gotten a chance to try with other media players. Is there a way to create an ap that autodiables jucedefender when you play music?

Not that I'm away of... I just manually disable juicedefender before I start playing my music... and HOPE that I remember to turn it back on...

I am not endorsing this battery/seller/etc or that this is the battery to buy in any way. Just came across this opportunity and wanted to put it out there for anyone that wanted to check it out:

[HOT!]Charging problems, false drain readings, dialer issue, battery life, SOLUTION

Hey guys,
I would like to make your situation easier, so you don't have to read like 1000s of forum threads to get information I'm giving you here. These are the issues I faced with my incredible s, and the so called solutions.
The device:
Stock EU htc incredible s/ htc droid incredible 2 on Gingerbread. NO software mods at all.
According to my knowledge the same applies to the htc desire s and the htc desire hd as well. Most of these problems come forward after updating to gingerbread. If you are still on froyo, I wouldn' recommend updating.
1st issue. High standby drain.
According to Currentwidget and battery monitor my incredible s doesn't have lower battery consumption in standby than 38Mah.
Solution:
Drain readings are corrupted, there is a bug involved.
In reality You only have around 5-6Mah drain in standby.
Proof.
Left phone in standby for 2 days without messing with it, ended up with 40% left.
So if you have a minimum of 40Mah drain for two days. (48hours x40Ma=1920Ma) The battery's capacity is no more than 1500Ma, so it's obvious that standby drain readings are corrupted.
IGNORE drain readings!
2nd issue: You take it off the charger and it's 95%
Some say that phone charges till 100% than shuts charging down till battery reaches 90%, than charging starts again.
Some say our Lithium battery cannot get charged till 100% which is normal. This is the reason our device doesn't show % in notification area.
Solution: Ignore battery monitor, use inbuilt battery charge indicator, and be happy.
If you want to test battery life, start test at 90% and your test won't be corrupted.
3rd issue: Dialer using too much battery.
This might to be a bug as well. Still to be confirmed. The dialer doesn't use that much of power it only gets stuck in built in battery use indicator giving false drain data.
Some say it doesn't stop using proximity sensor after being in a call, hence the big drain. Incredible s's proximity sensor is visible during call, check it in the dark, it blinks. After call it stays inactive. So the dialer using it 24/7 seems to be a false statement.
4th issue: Declining calls in pocket.
When taking or declining a call, you swipe vertically on the screen. If you have your phone in your pocket with the screen facing your body, you can easily take or decline some calls when pulling out. This is more likely if you have a pocket made of thin material.
Solution: Put your phone in your pocket with the battery cover facing your leg. Don't worry about bumping into like a table corner and smashing your screen. Our gorilla glass is almost indestructible. Using a pouch or cover does the trick as well.
Not sure why htc is so obsessed with the vertical answer procedure. With horizontal swipe we wouldn't have this problem and users have been complaining about this since the desire came out.
5th Issue: Wifi disconnects when signal low, but still would be fine under froyo.
Connection gets disconnected when signal is 86db or lower.
This is a gingerbread related problem, htc cannot do anything about it.
No solution just yet.
For those who complain about battery life, I am on gingerbread with loads of apps installed and with very heavy use 3hours of display, wifi, skype,internet browsing I can use the phone for 12 hours. With moderate use min 2 days.
Battery saving tipps:
-Don't let google and htc sync. It uses lot of data and battery resources.(I don't like my sensitive data to be copied on their servers anyway.) Sync with your pc regularly.
- If u use data for e-mail and weather sync, use Gsm only mode, you don't need that much of speed for those, turn WCDMA on if u need it for skype, etc. Hspda and 3g are big battery killers.
-Everything on manual sync. There is a sync all widget in sense to use. U can hit it anytime you want to.
-No live wallpaper
-Hotspot uses excessive amount of battery. Use it on charger only.
-Screen light to be turned down. Use Screen filter app nighttime.
-Turn wifi and mobile data off when not in use, so phone can sleep properly. (wifi timeout app)
-Turn off wireless network positioning.
-Keep bluetooth off when not in use.
-Select short screen timeout like 15s.
-Screen on time is the main culprit in appalling battery life. Use your watch to check time rather than turning the screen on.
-If u struggle to find 3g or Hspda for data or network itself, change provider, because no matter what phone u have, u will have this problem. Try to find spots in your flat with better signal for data. Searching for network uses a lot of battery.
-Try to charge your phone from 0% overnight with the phone off for a couple of times (8-12hrs)
-When gps is on it doesn't mean that it uses battery. If you see the sattelite icon blinking or just on, that's when it uses battery, a significant amount of battery.
-Consider buying the official extended battery available in US (droid incredible 2 2100Mah), coming to EU soon. I wouldn't recommend buying the unofficial ones just now.
Obviously if you apply some of these battery life will be better. If you apply all of them, battery life will be exceptional.
Hope I helped.
Have fun guys!

Hi!
Thanks you for this! I buy my incredible s a couple of days ago, upgraded instantley. I met most of these problems and now I am happyer with my phone knowing these.
Could you give link to the battery you wrote about???

i appreciate what you're trying to do - but if you are going to follow all those steps you might as well have bought a nokia 3210
"Use your watch to check time rather than turning the screen on"
i mean.... really??

As I said, you don't have to follow all the steps.
You might face conditions when you need every drop of your juice, so it's good to know how to get the most out of your battery, isn't it?

It's for the droid incredible 2, but thats equivalent to Incredible s.

Sorry if this seems sarcastic, but if you're gonna buy a smartphone and turn everything that makes it a smartphone off, then save yourself a few hundred quid and buy a Nokia 1100
I use mine to sync everything and anything I want, and don't worry about it, as long as it lasts the day, which it does, I'm happy.

you misinterpreted what the op said. He is just stating what you could do if you found yourself in a situation where you had to maximize battery usage. Obviously most of us are around an outlet or usb plug most of the day so that we can charge the phone often.
Thanks for the info OP. I just wish that current widget would show us the right info. Or some other app :/

Thanks for the info OP. My buddy has had endless problems with his Incredible. I'll Chrome to Phone this thread and send it to him!

Its not the apps fault, the phone just reports wrong. So any other app should also fail.
@superman, perhaps a faulty app is causing the problems

Wifi issue should be resolved with the ota update.
However there is a network at my workplace which I couldn't connect to. I guess it is some kind of wifi repeater, it doesn't look like an actual wifi router. There is no cable connecting to it. Apparently I can connect but I get 0 signal next to it. Others can connect with full signal. Any idea?

It is FAR from "almost" indestructible. Some people also say it's impossible to scratch it, yet mines been scratched (this AND nexus one) It's nice glass but indestructible? I think not, not even "almost"

Live wall papers do eat your battery, but it's almost close to nothing. I've read that whatever uses more than 2% of your battery will be displayed in the "battery usage" I've used live wallpapers and it's never even shown that. (I think it also depends on what kind of wallpapers you use though.. let's say you had one that interacted with you) perhaps that might drain more battery.. but who turns on their phone to play with their wallpaper lmao
I've tested and disabling google sync barely makes a diff. I also don't think it uses a lot of data. I don't completely disagree with you though, manual sync is probably a better idea. On the other hand, I don't really think Hspda/3g are big battery killers, I notice that if you use the browser, the battery drops quick. Let's say you used "gsm" / "2G" and the webpage takes longer to load whereas 3G would have it loaded within seconds.. Which would waste more battery? I'm not 100% sure but I'd say just keep 3G and turn on 2G if you're not doing anything else with your phone. To my surprise, 2G is horribly slow.

Completely false. This is only a cover on top of your screen. It doesn't change the power being outputted to the screen. If you look at what RogerProdacter is making, you'll see that he's trying to modify the phones brightness output.

Disagree again. It's really up to user though, that's insane. I'd be pissed if my phone kept shutting off in 15s! What you can actually do is turn off the phone yourself or get something like Lock screen widget which instantly turns off your screen. Two reasons it's better - You don't have to worry about the timeout - you shut it off sooner than 15s.

I don't know what kind of world you live in, sounds way too good to be true. Just instantly change providers eh? Where I live.. that's not really easy to do. I'm sure most people getting cell phones would have enough common sense to pick something that works in their area anyway.

[Q] Battery Problem??

I dunno whether it is a battery problem or what but I got a brand new battery
coz the last battery was too bad but the new battery also sucks.
I was wondering if it was cause of the ROM and kernel so
I switched to stock rom for trial purpose and still I got juz like barely 7 hours of juice....
with juz some files thru bluetooth and half an hour or so of texting....
so what could be causing the problem?
Here's the battery stats...

I'm not really an expert on this... but I'll try!
First, data - depending on how often your apps that use data refresh, it may be killing your battery because they are always updating in the background
Next, apps - depending on how many are open, and trying to retrieve info or a responce, this may be killing your battery life
Another, backlight brightness - I would say half brightness looks almost the same as full brightness, so turn that down too. Another thing you can do is make sure that your phone times out so the screen is always on and sucking the life out of your battery
Plus, bluetooth and wifi - turn those off when you aren't using them! They turn on in a couple of seconds so there is no use in just leaving them on and draining your battery.
Lastly, I dunno what "kik" is (the app running in the corner of the status bar) but it may be using battery too (probably not because it isn't in the list of the battery use so I don't think that's it.
Anyways, in short, possibly shut off the data if you don't always use it (you don't have to tho ), go into the settings of apps, and get the refresh rate at a longer period of time (so they aren't always using data), kill any open apps if you can with an app manager, turn down the brightness of backlight, change the time it takes to shut off the backlight, and shut off the bluetooth and wifi when you aren't using it.
Unfortunatley the battery life on the Ace is far from the best, if anything it's terrible, but other than that I have very few issues with the phone.
Well... That's my two cents. Hopefully it helps, but if not, search around on the forums and see if you can find any other solutions. :fingers-crossed: I'm not the expert, but I'm trying to throw ideas out there. Good luck

Running background processes is a major battery kill. I used to get 12h+ on 3G with Stocklite V6. Never used heavy apps though. Just Textplus, Opera Mini to check fb sometimes and WhatsApp whenever someone talked to me. Light usage.
How much the battery lasts depends on the user completely.

First of all thnx for taking this much time out....
It's rlly helpful...
but
1. My data usage is barely 10 mb per day....
and no wifi and mearge usage of bluetooth....
2. Background apps;
only adw and one or two others...
and Kik is juz like whatsapp, a messaging app....
and it's quite lightweight, been using it since uite some time...
3. Backlight is at an always 25% and screen timeout 30 secs....
so juz wanna know if there's a possibility of some hardware fault......
coz I've tried most things possible to take out the software fault if any....

Wait, i just forgot!...
I get this too sometimes, but what might help is if you reset your battery stats! I have to do this too because I found that after a half an hour after unplugging my phone with no use I lost 10% battery life, for no apparant reason. Search in the Play Store "BatteryCalibration". All you have to do is charge your phone to 100%, and tap the button . You usually have to do this after flashing a new ROM, because you might not flash it at 100% battery life and the stats go from there. So I would say, try it and see what happens.
Now... If not... The only other suggestion I have is if you find a battery booster app such as "Juice Defender" from the Play Store. I tried using it, but didn't see a huge difference (I don't have data, so I just keep it off), probably because I barely use my phone. I've also heard some thing about a script called "v6 Super Charger" (I've only heard of it, please search it if you want to know more because I sure don't ). Aparantly it boosts battery as well, but no promises haha.
If you are really desperate for better battery life, I would say switch to 2g service in the settings. Other than that.... I'm out for now
Hopefully this might help you out as well, but other than that the Ace is not well known for a good battery. But that's a mid range phone for you (but the Ace ain't no slouch either)
Anyway, goodluck!

Ok, so after looking around a little, I found a very interesting thread about Lithium-Ion batteries! Really cool and really worth the read! I learned quite a bit. Hopefully this answers any additional questions that I wasn't able to answer!

Try also eliminating any widgets or live wallpapers that you may have running. These might keep the processor running at a higher speed then neccessary, but no promises.... Plus I already mentioned closing apps you don't need (so this is pretty much the same woops) and you might have done it already.
The biggest thing to remeber is that you have to sacrifice performance for the best battery life. This may go as far as underclocking your maximum CPU speed, but this might cause some lagging especially at the startup. I think that this should be a last resort to be honest, because you still want to use a phone, and not a laggy device that you are trying to conserve as much battery as possible.
I also heard something about the motherboard possibly having a hardware fault in it causing excess discharge... But... I will need to do a little more searching to see if I can figure this out for you!
The other possiblity is that you get a power bank... But that just adds to what you have to pack around, so this is probably another last resort, but it's all up to you.

How to get the best sound quality out of this great phone?

I bought a Samsung captivate from a friend yesterday. He was running Kitkat on it and it is very slow. My only use of it as a phone is recieving calls and text messages, nothing else like facebook,whatsapp or anything. My main use for this phone is to use it as a portable music player as I travels alot. I saw an old thread from head-fi that, this phone can be transformed into an Audiophile level music player using a Voodoo kernel and an Voodoo control plus App. But that was in 2011. What is the current situation? How can I get the best sound and best battery life out of this great device? I mean, which rom or kernal or modes to get the best sound quality out of this phone?

I use DSP Manager http://android.appstorm.net/how-to/music/install-and-configure-dsp-manager-on-any-rom/ It seems to make better sound than the stock sound driver. Battery Life on the other hand I'm not too sure about, and I have used 3 different batteries with the same outcome. You could wipe battery data
TheYar said:
Erasing the battery stats (for you rooters/flashers)
Sometimes you just want your phone to forget everything he thinks he knows about his battery, and re-learn it from scratch. Your phone maintains a file with statistics on battery usage, which in turn is used to help calculate battery life at any given time. Sometimes, especially if you've been playing with ROMs, kernels, and lagfixes, the stats in the file just aren't applicable anymore to how the hardware is being used, so you get crazy battery drain.
Clockwork Recovery has a simple function to wipe the battery stats. If you can't run Clockwork, use ADB or a terminal emulator (search the market) to delete that battery stats file located at /data/system/batterystats.bin. The link at the bottom to joeybear's thread has a little more info.
The general idea is to start by trying the above - make sure it isn't your own fault or maybe just a bad battery, then drain, bump charge, and wipe stats - in that order.
There are lots of ideas about what may or may not happen when you experiment with the above. Wiping battery stats after a ROM flash that already wiped them for you is at least redundant and may even contribute to a battery drain problem. Some say you should wipe first and then drain and bump charge. Be careful about wiping stats and bump charging too much, though. Over-charging your battery will hasten its demise.
HOWEVER, if you're like I was when I first started this thread, you've seen the above recommended many times, and none of it has ever helped you one bit with an actual sudden battery drain problem. http://forum.xda-developers.com/showthread.php?t=765656

I bought a Samsung captivate from a friend yesterday. He was running Kitkat on it and it is very slow. My only use of it as a phone is recieving calls and text messages, nothing else like facebook,whatsapp or anything. My main use for this phone is to use it as a portable music player as I travels alot. I saw an old thread from head-fi that, this phone can be transformed into an Audiophile level music player using a Voodoo kernel and an Voodoo control plus App. But that was in 2011. What is the current situation? How can I get the best sound and best battery life out of this great device? I mean, which rom or kernal or modes to get the best sound quality out of this phone?

I use my old captivate strictly as an mp3 player using the captivating X8.1 rom and devil kernel. The voodoo sound app is still kicking around the Web I'm sure.
Instead of using the headphone jack, I made a line out cable that plugs into the charge port and on the other end of the cable is a line out 3.5mm jack and a regular USB plug to charge at the same time. All the info for wiring and resistors to use I got searching around this forum and the "fun with resistors" thread in the i9000 forums.
Using Power amp for my player app, with all other non essential apps removed, and in airplane mode with WiFi enabled I get about 15 hours of music from my own collection on a 32gb micro sd card. It can also play wile charging with minimal or no noise depending on the charger used.
It really makes a great mp3 player.

Thanks for the help, both of you.

Alternative to Google play Music

So all my music is online on Google play music but GPM is draining too much of battery, is there any other player to play the music that is stored online on my account in Google Play Music?

Nope. How much drain are we talking about here?

Like a 2 percent every song drain

I played the following three songs, in order, from "Dr. Demento's 20th Anniversary Greatest Novelty Records of All Time". The battery started at 87% on the first of the three songs and didn't hit 86% until about half-way through the third.
The Scotsman (2:27)
Junk Food Junkie (3:05)
Eat It (3:20)
Something else is causing your battery drain. You'll need to investigate and see what's causing it.

It most likely relates to his signal and google music trying to stream it. This is part of of the same reason no one where I live use streaming apps like that. Signal will eat your battery alive. 99% of people here you will find keep their music on board.

Good point about the signal.
I happen to be that 1% that streams my music, though I still have an MP3 player just in case.

When I said 99% I was talking about the people around where I live. Due to many factors, not the least being location, signal here sucks no matter the carrier or device. So keeping many things on device is still handy here. Most devices sold still have an SD card slot. One bonus is that one carrier here sells only European device models even though we are in the states. So we have a good selection.

When you said "here" I thought you meant "here on XDA".

I kinda figured that from the reply:highfive: I wouldnt be surprised if many on XDA still did. With the data limits in some countries, it would have to be a complete pain to stream anything let alone reliably.
As to stay on topic, Any streaming service will eat battery. Mainly if signal is weak or unstable. So my advise would be to do what I ended up doing. Get an OTG flash drive and keep your whole collection with you.

Well it's not my signal because when I use Google play music and even after than it somehow keeps running in the background and when I see my battery stats, GPM has somehow taken 2 position next to screen in draining battery, I'm on Cm14.1 with latest elemental kernel running and I get about 3 hrs of sot, any better options for kernels?

If you have the premium version of Plex you can stream media (like music, movies, tv shows, etc...) as long as your plex server is up at home and have working Internet. Not sure on the battery drain vs Play Music. I personally use Spotify and stream everything but obviously that's a paid service.

I cant say anything about SOT. I dont keep track of it nor is it a big factor for me. My biggest usage of my device is with the screen off.
I would get something like Better battery states and see if you can track it down from there. It could be the media server issue that CM has suffered from for years but without a deeper look you really cant be sure. Also grab a logcat app and see if something is going on in the back ground.

I got the alternative, it's Tomahawk player, it's actually really good, and doesn't seem to drain that much either, another one is GMusicFs, but it doesn't seem to be working on Nougat

Why don't you just download your music to your device from GPM?
