Galaxy S4 issues

[Baxteen]

I have not had a single one of the known bugs with my S4, no reboot on camera app, no battery issue and no wifi issue.

I did root the day I got it, installed titanium backup and removed close on 8 gig worth of crap that came pre installed.
one thing I did notice in one of the android communities on google plus, similar issues were pointed out and in 90% of the cases the issue ended up being custom battery widgets. if you have any sort of battery monitor, saver, or widget uninstall it.

also in order to provide the most help consider posting a screen shot of your battery statistics from the main menu where it shows what used how much (setting ->more->battery)

from there we might be able to spot what app it is that is causing problems.

on sunday my battery only lasted 2 hours from fully charged, but I was playing worms while downloading 2 movies via utorrent app (afrihost apn for the win) and my phone was a wifihotspot for my laptop that was streaming you tube.
so I dont think that was a battery issue that was me abusing the phone.

Sorry forgot about this thread!

What did you end up discovering with BetterBatteryStats?

I downloaded it, but not sure what I should be looking for, can you help?

The best way I found is to charge your phone fully before going to bed, unplug the phone, then when you wakeup you open BetterBatteryStats and check under kernel and partial wakelocks what was keeping the phone awake.

Don't know if this will help much, but here we go:

BetterBatteryStats is going to show us why Android OS is using so much battery, just a comparison for you, my phone has been on for 1d 18h 39m and Android OS used just 24%.

OK, I'm going to try to charge it fully when I get home tonight.

Last night I unplugged it after it was fully charged and went to bed. I think that was around 10-ish. This morning when I left the house at around 06:45 the battery was on 18%. :wtf:

The OS is definitely doing something fishy!

That's something majorly wrong, if I fully charge before bed when I wakeup it's still at 96%.

I've come to accept the fact that the average battery life of my S3 mini is 10h. Everyone I know with a Samsung has bad battery life.

Got it!!! It was my memory card

Right, wife had to charge her phone last night so I unplugged it when it was at 88%.

Forgot to check where I was when I started messing around on the web from around 4:45 until around 6 when I got up.

Here's a screenie I took at 8



I did some reading up last night and with the help op BetterBatteryStats I was able identify process as mmc2_detect. Then it crossed my mind that a week or so ago I was copying a movie over wifi to my memory card. I then realised it was a stupid idea as the movie was about a gig in size and I have a very slow (class 4 I think) memory card. I couldn't cancel it as it appeared to have frozen, So I had to take out the battery.

This caused the phone to corrupt the MC and this process was trying to read the MC the entire time and thus kept the phone from going into deep sleep.

Thanks for all the input!!!

I am glad there was a resolution to this.

just one question, if you are going to copy things from a PC to the card, why not simply take it out and put it in said PC? most cards come with adapters and most laptops have a MC slot, I completely understand if you have a PC and no way to do it.
I am just curious and I am not trolling here I am just trying to understand the logic that is all.

PC and a laptop is 2 very different pieces of hardware. While most laptops do have some form of card readers, very few pc's have card readers as a stock item.
The pc probably did not have a card reader attached.

Sorry fo0r the late reply. The movie was on my HTPC which is actually spare P4 I converted, it doesn't have a MC slot and I don't have a laptop

Don't leave your phone on charge over night. In fact, if your S4 or any phone is new, it normally doesn't take long to charge fully back up as the battery is still very much in its beginning stages. Leaving your phone in the charger to charge over night will just eventually kill your battery, as you are over charging the battery. Also be careful about installing these battery apps, some of them does more damage to your battery.

Ensure that WiFi and Bluetooth is off. Ensure that you don't have anything set to auto sync, and rather go and manually sync your apps etc. Eg, set your emails to sync manually or say every hour or so etc, instead of pushing. Disable location services if possible, and also if you are using things like Facebook and Twitter,set the refresh rate to at least 1hr or so. Some people have their twitter refresh every 5 to 10 mins in, and this causes the app to refresh at that rate. Its also important to install apps that will be of benefit to you, and uninstall apps that you don't use. I've seen people with more than 60 apps, and they probably use 5 percent of those apps.

The other crucial thing which will destroy ur battery is live wallpapers. While they may seem pretty, try not to use them, if will kill your battery.

As far as I know, charging overnight is no problem - the phones have circuitry to prevent overcharging. I'm doubtful charging overnight will have any noticeable side-effects over the lifespan of a modern phone.

About the live wallpapers - I've been using them for months and the impact on battery is non noticeable in my experience. The live wallpaper process is only active when you're looking at your home screen, which isn't all that often. That said, I'll maybe try a static wallpaper for a few days to see if I can spot better battery performance.

Live wallpaper has neglible impact, and wifi on actually saves battery compared to being connected to 3g.

Can i ask where you get this info from, would like to know more if possible. I'm no expert myself but as far as I know recharging a lythium ion battery overnight has no affect to its longevity. Are you sure your not just taking the precaution used for alkaline batteries here. I can understand that if you've just been told to not overcharge batteries because that is a terrible thing to do and seriously messes up the battery but i infact study these things so it is in my best interest to know although not essential so why i ask if you have a source i can read cause i may be wrong. However what i know is alkaline batteries just lost the abbility to charge if you overcharged them. But if you overcharge a li ion battery it will expand due to gases being produced inside the battery. Because of this there are safe guards in the battery to prevent overcharging. So extended charging isnt really a problem as long as you use the recommended charger as it regulates current to the battery so it never overcharges. The killer is over volting, this causes the battery to expand more violently and can even make it explode if done repeatedly. Same with overcharging but takes longer as the capacity build up over volts the battery in the same way but not as much as directly over volting the battery. Over volting is just supplying a voltage greater than the recommended voltage. But even some phones these days have protection against over volting but leaking the extra voltage away. So the only killer really is overcharging, and this only really happens if you use a non certified charger. So if you use the certified charger it doesn't matter how long you charge the battery for. This is what i know. Just talking about the overcharing, everything seems to be spot on, dono why people use live wallpaper anyway, very pointless.

I think it's a balancing act, if you're going to disable everything then just get an old Nokia phone. Everybody does not need everything on all the time, but I think disabling auto sync and live wallpapers is a little extreme. I agree with reducing refresh times for Facebook, Twitter, etc (unless you use them a lot) and uninstalling unused apps is definitely a good idea. Keeping a fair number of features on (including Air View and Air Gesture) I get a full day. I think a better way is to look at the running apps (in the Applications setting) and look at what's continuously running and disabling the stuff that you never use.

 

[cryaxxx]

OK, I hardly ever use it anyway.

Downloading it as I type this.

How do you turn it off? Where's the option?

To give you guys an idea of how bad it is: At about 9 this morning I plugged the phone to charge it via USB. It was on 19%. When I unlcoked it now the fscking battery was on 17% :wtf:

That means that whatever its doing, it uses so much power that it negates the 5 volts from the USB!

What charger you using the stock one? And dont charge using usb not enough power.

 

[nicbst]

Technically it's using more than the charging current that usb can provide, which is about 500mA if I recall.

That being said I regularly charge mine via usb while using it and it charges fine. You might have a faulty battery like some others.

I have no gimmicks enabled and the only apps I run are whatsapp and bbm; I don't see a huge impact on battery life.

 

[Furbz]

Just to add to this. Samsung had a bad batch of phones go out. Remove your battery and check if it it swollen. Easy way to check if you can't see it by eye (mine is quite obviously bloated) take the battery out and spin it on a table, if it is still flat it won't spin much, if it is bloated it will spin like a top!
