[Q] A couple of noob questions - EVO Shift 4G Q&A, Help & Troubleshooting

I'm new to this phone, and still learning my way around a bit. A couple of items that I'm wondering about...
1) When my battery starts getting low, and it goes into power saver mode, there is a button I can hit that says "Battery Info." It seems to almost be like the battery history in Spare Parts, which is nice, since Spare Parts doesn't work. However, I'm not absolutely certain how to interpret this data. Is it telling me what percent of my battery drain has been due to certain apps? Or is it telling me what percent of the time they have been running? Also, how can I get to this information when I'm not in power saver mode?
2) On a related note, what is considered to be typical battery life for this phone? I know that's a completely loaded question and differs by use. But maybe like a min/max range? And what things can I tweak to maximize battery life?
Many thanks.

1) to get into the battery stats go into Menu*Settings*About Phone*Battery*Battery Use* and its my understanding that the percentage shown for each app/task shows how much of a percentage of the battery that has been used was used by said task so right now my display shows 58% and im at 36% battery so 58% of the used battery was due to my display, then if i click on display it shows a time for how long an app/task has been active, so in my case phone has been on for 9 hours and display has been used for 4 hours i hope that helps
2)Battery life on the Shift is pretty solid im still at 35% and my phone hasnt charged since yesterday at about 6pm and i used it till maybe 2 am went to bed no charge woke up used the phone for about 30 minutes and have been on tapatalk and gtalk, facebook...the longest standyby i have had with my shift is 48 hours of very light usage but i normally get about 8-10 hours of extreme usage, so if your not a power user you should see some amazing battery life

Awesome. Thanks. That battery history thing blows Spare Parts out of the water.

[Q] 9hrs unplugged, 44min display, 3hrs run time, 40% battery left

I have been having problems with my battery life pretty much since I have had this phone. I downloaded spare parts app to give me some insight because I have also noticed several times phone seems warm even when screen has been off for some time.
As of right now today, to give an example, my phone has been unplugged for the last 10hours and I only have 44% battery left. Says display is responsible for 71% of battery use yet screen has only been on for 44min of that time (and I have the brightness turned all the way down). According to spare parts "other usage" my "running" time is cause for 35% of batter use at over 3hours.
With these things in consideration I feel that there is something that is stopping the phone from properly sleeping due to the phone being warm at times display has been off for a while and the contrast between screen on and running time. Partial wake usage doesn't show much running under it as most listed items have only a sliver of a bar showing.
Can someone please lend me some guidance on how to further troubleshoot this problem?
i mean that type of battery consumption doesnt seem irregular to me...im at close to 10 hours for the day and have 59% left.
Are you in a shaky signal area? Thats one reason my phone gets warm. especially if its a fringe area where it cant decide between a 3G signal or 4G signal.
In spare parts there is a option for partial wake lock. If something is stuck at 100%, then you know you yuo have a rogue app thats causing your phone not to sleep
But can you confirm it being normal to see 34% time running under other usage settings for spare parts? Partial wake usage as said doesn't show much keeping a wake lock going.
As for signal, not too sure, very rarely if ever see a 3g change over. Is usually at 4g and occassionally hitting edge.
WOW, you get that good of battery out of yours? that seems epic haha, i get 3-4 hours tops.. i mean i abuse it, but still..
I charge mine at night. Ran it from 7am to 12am and it was at 34%.
Yeah see...7am to 12am and 34% remaining? No way I get that.
If it werent for the results I'm posting regarding "running" percentage from spare parts other usage and the screen on time I would just accept it as a phone deemed to have bad battery life, but it seems to me like something is going on and I guess I'm looking for someone to confirm or dismiss my suspicions.
Maybe I'm also a little spoiled coming off my G2 that was rooted running CM Rom and CPU ramping/cut down which in combination gave me, under the same amount of use, a situation where I was getting home at night and still having 40-50% battery left in comparison to the 15% I commonly see now.

once some custom kernels come out that let you uv/uc/oc then i would say you can expect the same type of results..i just went on a trip with a friend who has a g2 and he was constantly crying about his battery dying, (stock), where as I only had to charge mine on average 1.5 times a day with moderate to heavy usage. I find this battery phenomenal compared to all the other android devices ive owned and tested
damn!
i charge mine every other day.. hehehe i dont abuse it or anything though.. just regular internet every few minutes or so.. i have the BETA juicedefender installed guess that helps a lot. data is off when the screen is off, set it to agressive..
here is the app hope it helps...
I noticed the same problem,i brought this phone on saturday and was very impressed with the battery until yesterday night I noticed the same thing, my phone was at 50% and I had it sleeping then I get the battery low notification 10 minutes later and the back of the phone was real hot. This can't be normal cuz I have the same apps installed from 2 days ago and I was using the phone heavily even using mobile ap and still didn't have this problem, if you guys find a solution please share it with me.

[Q] How Many Times Did You Calibrate Your Battery Before You Gained Full Potential

I am now on my 2nd full charge. Drained completely and full charge while off. I have the battery calibration app and i use it. Im about to take my phone off the charger and put it to work.
How many times did you calibrate your battery before you got the full potential of it. I see some people are getting as much as 30+ hrs on their device while im getting 7-9 on moderate use.
I've never done that. Always read that draining lithium-ion batteries hurts the battery if done repeatedly. Instead I just charge to full then delete battery stats in clockworkrecovery. Battery has been great ever since that and a factory reset.

What does deleting the battery stats via ClockWork do? Do you delete them on each charge?
I was getting great battery life and then I used the calibration software and I'm getting good, but slightly less great battery life. Does uninstalling/freezing that app do anything or once it's calibrated, it's done?
The phone has a dual-core processor, and the best GPU you can get in a phone these days, so you can't expect it to get super battery life unless you never use the phone much. I did the calibration once, and have been able to go all day under moderate to heavy use. All day being 8am-7pm and still having ~20% charge.
Sadly my first g2x that I received wasn't able to go through more than 4 hours of standard use even after fully charged the 2nd time. I sent it in last Friday for exchange and now I'm waiting for the 2nd g2x to be send to me. Well see how it goes by then.
@himmelhauk - I noticed in your signature that you have the Paul O'Brien fix... I saw in that thread that that noticeably increased speed/smoothness, but I haven't heard anybody talk about its influence on their battery. Have you noticed a difference in your battery life after making that tweak?
Me
I only calibrated once, and that plus some other simple tweaks i saw great results. I usually get about 20+ hours of medium use(A few calls, non-stop texting, occasional game or youtube video, and checking email every couple of hours). If you want to see what I did you can click the link in my sig.

it gets rid of the battery information stored within the os so that the phone reads the battery charge correctly. this was common practice for vibrant owners after flashing a new ROM. I've seen people saying that this phone has horrid battery drivers so I dunno how that will effect the battery stats but after a factory reset and deleting the stats my battery is double what I was getting on my vibrant.
I only do this after flashing a new ROM or in this case upon getting and setting the phone up. I would do it again if I swapped the battery for a different one also. just charge to 100%, reboot into clockwork, advanced menu, wipe battery stats, done. it DOES NOT increase battery life. it only allows the phone to read the battery more accurately which would keep the phone from thinking its dying when it still has considerable charge left. that's why you hear about people seeing their battery life read 1% yet the phone last for hours.
I only calibrated once because I realized the values were off a bit.
Tried every battery trick in the book. If you actually want to use the phone, nothing will help. Android is a battery eating nightmare. Hopefully one day the platform will mature so adults can use it as a business phone. I think I am returning mine or giving it to my kid.
I did a single calibration and am now seeing 20+ hours with decent usage. Fully charge the battery, use battery calibration app to erase settings, let it drain till it shuts itself off, try pressing the power button to make sure there's no remaining charge, then fully charge to 100% with the phone still off (you can tap the power button while its plugged in and off to briefly bring up a battery indicator on the screen with out actually powering up). Its true that lithium ion batteries last longer if they don't go through fully discharge cycles, but thats referring to repeated occurances, not a rare or occasional situation. And when calibrating, draining from 100 to 0 is the best method of getting a good calibration. Additionally, while its healthy to do the mid charges most of the time, about once a month or so you should do a full drain. This helps keep the calibration accurate (remember that android will continue to modify the file, albeit at a greatly reduced level after the initial discharge of a new calibration, hence why that occasional full discharge is valuable). A full discharge once a month won't significantly reduce your battery's life expectancy.

Draining a li-ion battery past the safe shut off is an easy way to damage or completely kill the battery. Your phone is set to shutdown before complete discharge for this reason. The full discharge then charge method was for NiCd batteries. This has no use for lithium-ion batteries.

True, but the method of attempting to power back up won't actually drain it past the safe point. The point is bad calibrations (either from the factory or by an incomplete calibration) can cause the OS to shut the phone down prematurely during your new calibration run (before the actual safe cut off), resulting in the calibration being off scale. When you attempt to power the phone back on, if it is at the true safety cut off, it won't reactivate, where as if the calibration from before was skewed, it will allow it to boot back up and finish draining down to the safety cut off. This is in line with the reports of people having incorrect readings on battery %, where they have a low number, reset the phone, and suddenly seem to jump up 10 or 20%.

I honestly don't know if it made any difference on battery life, as I did the battery calibration before I installed the fix. At any rate, I get much better battery life after the calibration for certain.

I dunno about this phone but I know the galaxy s can still be powered on after the safe shut off and drained completely. People were doing exactly that and messing their batteries up. I would hate for people to misunderstand your post and end up making the same mistake. So the LG doesnt let you power on after the safe shutdown unless its connected to a charger? If so thats pretty good. In any case its a lot easy to just use clockwork, terminal emulator, or any other app to delete battery stats once your charged to 100%. No need to drain first

I hadn't heard about the Galaxy S phones having that issue. Like I said, I came from the Eris and this method was the way to go with that phone, so perhaps its a manufacturer dependent function. In any case, I agree that the cwm method is better, but I meant my post to be accessable by those who may not have taken that particular plunge yet, since it only requires root. Thanks for the info though; its good to know in advanced that the safety shut off being unavoidable isn't a guarentee on all phones (though frankly it should be).
EDIT: Not sure if I'm reading it wrong, but it sounds like you thought I meant to drain the battery before calibrating, which isn't true; all you need to do precalibration is have the charge at 100%. The only time I was suggesting to drain it is during the actual calibration run, so that Android has a full scale of your battery's range. If thats not what you meant, than ignore this edit. Just wanted to make sure I was explaining myself correctly.
Also, if you open your battery cover and look at the battery, it's not suppose to go above 40 degrees celsius, or 104 degrees fahrenheit. I found that the temperature often goes past this, especially when watching movies for extended periods of time, or playing games, which leads to a significant decrease in battery life because heat and li-ion batteries are not a good combination.

You can use SetCPU to make a profile according to battery temperature and underclock it when it gets to 40 degrees or something. I have profiles for when the screen is off and for temperature.

[Q] Disappointed with the battery life... :(

Hi folks - this is the first thread I have started, hence requesting the non-noobs to go easy on me... (this forum is a scary-kind-of-cool)
I mustered up the courage to install Infused 1.5.0 on my stock... the instructions were superb and everything went great... really enjoying the improved speed and looks. But my battery life has degraded. It has been more than a week since I flashed my phone - and it is only getting worse. Now I have read a lot about how Infused is getting great battery life for some folks... and i have gone through those threads, trying to figure out what I am doing wrong. This is my typical usage profile
1) I put the phone on charging before I go to sleep... when I wake up (around 7 AM) it is fully charged.
2) I quickly check overnight messages, finish the daily ablutions, and 30 min later when I check the phone it is already at 95%.
3) By 10 AM, I have made a few long phone calls (no bluetooth) (totalling 60-90 minutes) - and the battery is down to 75%
4) At work I use a bluetooth A2DP headset - maybe 30-40 min of calls and by 12 I am at 50%.
5) More calls in the afternoon, intermitted mail checking and sometimes 30-40 minutes of music streaming on my bluetooth headset - and by 6 PM my phone is down to critical level 12-15%.
This is in now way the same experience that others are having with the Infused ROM and with the Infuse phone in general.
Other points:
6) I run Juice Defender... (don't know if it helps)
7) My screen brightness is just a few notches over 0%
8) My data is always on - except when I am using Wifi of course
9) I turn bluetooth off when I am not using it
So that's the story guys... and I would eternally grateful if the awesome folks out here can help me figure out what I am doing wrong... or there is some logic behind the sad battery life of what is otherwise the best phone that I have ever owned.
It depends how long Infused has been running on your system. After about 3 days I noticed my phone was adjusting to the ROM and the battery life improved significantly. Aside from that, try this trick. Drain your battery next to nothing and then charge all the way. Do this a couple of times. Not quite sure about the logistics but it seems to work. Another thing that has improved my battery life is to make sure I don't have background apps running. You can check this by going into apps > manage apps > and then running. Sometimes Media Hub will begin a background process and that eats up a whopping 8 MBs alone. Force close these pointless background apps and you should see an improvement there as well.
have you conditioned the battery and reset battery stats?

Thanks popesmasseuse (you really aren't are you?)... the ROM has been running now for a week... gets worse rather than better. I do typically wait for my battery to drain completely before I charge it... but when I do have to do it at 7 PM - then I can never charge it fully, before I have to start using it again. I wonder if the fact that my phone goes through "micro charges" is a reason for my declining battery life...
Will check the running apps... and see if closing them improves things... thanks!
Fact: Installing a ROM greatly improves battery life... Try it....
Turn of GPS and Bluetooth when not in use.
Same here I uninstalled media hub... period... just useless...
Phone calls are a pretty heavy battery drain. Sounds like you're in call for hours each day. Most people don't talk on the phone more than a few minutes a day. Poor signal will also significantly reduce your battery life... how many bars you usually have at work?
My battery life got better the longer I had the infused ROM. But personally I only talk on the phone maybe a total of an hour each day, but I am constantly using internet and youtube, and if I have spare time I'm using my Kindle app to read some books. I keep my GPS, sync, and wifi on all day long and my brightness all the way up (I just can't stand a dim screen lol) and by the time I got home today my battery was at 40%, which I am perfectly fine with.

Ah...the man himself.
Yes I talk a lot on the phone - nature of the job. 3 hours minimum in a day. Signal at home is terrible - 15% strength... that could be the reason why the battery runs dry after the morning routine. Any way to offset that?
At work signal is great. But in office I also tend to use my desk phone more...

Read the thread in my sig.
Never use task killers.
For me, battery life on phones gets good after about 2 weeks or so.
With light to medium use I can easily go for 2+ days.
Consider not streaming music through Bluetooth. Also don't auto sync stuff every 15 mins. If you can use Gmail they use Push notification. I'm on my phone all day literally and I make it home with some battery left. BTW connect to a Wi-Fi when ever possible, 3g data streaming will kill your battery quick.

It's a Lithium-Ion battery which means it does NOT respond to "conditioning".
"Reconditioning a battery involves completely discharging the energy from a battery then recharging the
battery. Li-Ion batteries do not require reconditioning to maintain good battery performance since Li-Ion
does not have a memory effect. It is necessary to complete drain and then recharge a Li-Ion battery in
order to determine its current capacity level, but that is not the same thing as reconditioning the battery. Li-
Ion batteries do not have a condition that needs to be reconditioned." lxe.com

Keiht's tutorial is effectively a technique called "bump charging" for putting that last extra percent or two of charge into a battery. However - with Li-Ion batteries, charging like this will SEVERELY reduce their charge cycle lifetime.
The only thing that "calibration" should affect is how your device reports battery charge level, NOT actual power usage. You should get the same total battery life whether your device is "calibrated" or not, with the exception possibly of the device shutting off prematurely because it thinks the battery is lower than it really is.

I would have to agree with you. I followed his directions as i was having horrible battery issues after going to 1.5.0 and it seems to have helped the reporting as far as I can tell. I think the big problem and it is only a guess is how the phone is reporting the battery condition not actual battery left. In any event I am running JD and the longer I run with 1.5.0 the battery seems to be lasting a lot longer but I have ti disable most everything which hobbles the phones best features to get that battery life still searching for the perfect solution.

Extended Battery

Anyone know where to get an extended battery? Thanks.
I can't even find a place to buy a regular battery for the phone. I'm not sure if I would need one, but it would be nice to have. I'm in the habit of charging it the last hour I am at work so no matter what, I'll never run out of battery even if I go somewhere straight from work, but a spare battery is always a good thing to have.
I have a wild guess as to why not.
I noticed this phone battery has the "near field communication" labeling on the BATTERY. The other phone that I'm aware of having NFC, (the galaxy s2) does NOT have this wording on the battery.
Why did I notice this? I randomly read that there is an SD card manufacturer that is putting NFC chip's into their microSD cards, and even some ipod cases are getting NFC chips built into them as well.
I don't know too much about NFC, but with the labeling being on our battery, and not the S2, I kinda think our NFC chip is actually in the battery, and not the phone itself. If an NFC chip can be put into an SD card or case on a phone that never had NFC to begin with, I don't see why it couldn't be put into a battery, especially since one of the terminals might not even be for power, but just for an NFC connection.
That's my theory, I could be wrong!
you're probably right. This is how it is with the Galaxy Nexus, also built by Samsung. I hadn't noticed the label, but I also wasn't looking for it.
I'd be curious to find out what an "extended battery" for this phone would look like. I'd be all for it so long as it kept NFC and didn't bulge out of the back
I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery
I'd bet you a waffle cone your screen brightness is set too high.
Forget most of those "battery defender" apps, especially if they are those stupid task killing applications.....a program being in active memory is not necessarily actually doing anything, which means it is not using your battery, and if it gets killed, if the OS needs it open for any reason, it having to be re-opened will just use cpu cycles anyway
I'd agree with most people that using the automatic brightness option is very annoying, it's really sensitive and it also tends to make the screen not be bright enough. Having said that, using any of the many available brightness widgets can be a very good thing.
The stock one is not so bad, personally I've been enjoying powerful control, http://goo.gl/2vZXl but I've had great battery life and easy readability if I use the brightness setting where it looks like a half moon.
If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

My screen brightness is at zero without automatic brightness on, and im not using haptic feedback. The phone battery is fine if its just sitting over night, but as soon as I turn on GPS to use maps for 5 mins or to check facebook the battery just drops a % every min. So i guess the phone is fine if Im not using it, but then whats the point?
You're exaggerating.
I've never had a phone battery drop 1% per minute.
Look man, I just spent 5 minutes playing music at max volume, while getting directions to 8 different places in google maps, sent two emails, downloaded a new app from the market, and received one text message.
Battery level after all this? Still at 100%. Does that mean I can do this an unlimited number of times? No, it does not.
Frankly, I don't believe you. I've used this phone, and my previous phone for playing movies at full screen brightness with the audio being played through bluetooth to my stereo headsets. Does it effect the battery status? You bet it does.
Two weeks ago when I last played a snes game on my phone I did so at full screen brightness over bluetooth to a ps3 controller. When I wasn't playing the game I was sending or receiving text messages and had vibrate on. I played super metroid from the very beginning to almost through the end of the game. When I play snes games on my phone I tend to use quick save and quick load and frame skipping very commonly, effectively letting me do things "perfectly" but this is a lot of saving and loading and running the game even faster than how it normally is. I started at 2, and the next thing I knew it was 6:00 and I was supposed to meet a friend for dinner at 6:30.
But for crying out loud you are saying you can drain your battery from 100% to zero in less than 2 hours.
I'm calling shenanigans. I don't think you could even do that intentionally, unless you sat there and forced the phone to vibrate the entire time.
Phone batteries don't last for days like they used to. Batteries have not changed too much in the last few years, but the things phones do, and the screens they do them on certainly has. Stop expecting your phone to last over the entire weekend even when you actually use it.

I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery

Something to keep in mind:
When this phone hits 100%, it STOPS CHARGING. Even plugged in, it will no longer be drawing power into your battery, yet it'll still be running on battery.
If you plug it in when you go to sleep, it finishes charging within 2 hours, then it goes 6 hours idling on battery power but it still says 100% until you disconnect it. Then, while you're using the phone it'll adjust as you use it until it gets to the right level. This is likely what you're seeing.
If I use my phone from the moment it finishes upping to 100%, I get great battery life. I get great battery life in general and have been happy with the phone.
Of course, this might be a totally different issue where you just got a bum battery. But it's something worth considering.

I don't believe this is true. I hate to constantly be a naysayer in this thread, but this didn't seem logical to me so when my battery went to full, (when the battery is full, unplug charger text showed in the notification bar) I kept it plugged in and set it to play a couple tv episodes on full brightness while I did laundry and made dinner.
Two hours later, I first looked at the battery status while the phone was still plugged in. As expected, it was at 100%.
I unplugged the charger, waited a couple minutes, and checked again.
Still at 100%, which completely makes sense because I've never had a phone that behaved as you've described.
I also would have noticed the battery dying very early, *every single day* because my habit for the last week or so has been to plug the phone in when I go to sleep. I have an app called syncme that pulls files off my computer such as music and video while I'm sleeping, and on average it transfers about 6 gigs of data this way, every single day.
I don't know if you've ever transferred 6 gigs of data on a phone via wifi, but yes, it's not exactly battery power friendly.
My phone's always been 100% battery when I leave for work, just like my last phone was where I also plugged it in at night.
Just saying!
So you guys know.. I have galaxy nexus and the blaze and the batteries are the same so you can order a battery fro the nexus and it will work with the blaze

Just did an ebay search for Galaxy nexus.. You might need to clarify which model number as there are various Galaxy Nexus batteries listed per Nexus model on ebay...
Galaxy Nexus GSM I9250

Actually he is pretty close to the way it operates. The way your phone gauges battery life is similar to your car with gas. When the meter reads 100%, it is really more like 98%. When the battery reaches true 100%, the phone will stop charging the battery (but will run off of USB power, not the battery). They do this to account for small variations in the many variables that affect a battery's performance (like temperature). Likewise, your phone will read 0% before the battery is truly completely drained (this is also to protect the battery - they don't like being charged to 100%, nor drained to 0%).
This could also greatly affect your previous test on battery performance. To get a more accurate result, let the phone drain to about 60%, then test the time to drop a percentage point.
What you are talking about is a suggestion that the battery meter doesn't necessarily update it's strength meter all of the time, and you even say that the phone runs off the plugged in power at this point.....

His entire post is incorrect, and has nothing to do with what you are talking about either.

Before you discredit anyones post, you should understand how many battery chargers work, and the importance of them shutting off following a complete charge. Here is a quote regarding Li-ion battery maintenance :
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Many chargers have this feature built in to avoid any overheating and/or damage to the cell. I'm not saying this is the case because I have not tested whether the battery charging circuit in this particular phone, or it's charger operate, but I will say that this has been the case in MANY of it predecessors.
That being said, I think an extended battery would be a welcome addition to the options of this phone. Mine too only lasts a day at it's best. Perhaps not 1% a minute...but then again who knows?

I'm getting desperate with the whole battery situation

So I had the S6 last year and ended up returning it due to the poor battery performance. I ended up back on an iPhone. When the news of a larger battery and better chip performance come out for the S7 I was ready to jump back on the ANdroid bandwagon.
So fast forward. I just unplugged my phone at 100%. It's been a half hour and I'm already at 95%. I have to consistently keep the power save mode on to conserve battery. It's getting somewhat annoying because it screws up updates and notifications as well as some app don't work well.
I've tried conserving battery by shutting off certain features, keeping display brightness down etc while having power save mode off. It just seems that Android System is chewing through the battery. I don't know what the hell is doing it either.
I don't want to cripple the phone by keeping it on power save mode all the time. Does anyone have any recommendations that will help me or I might have to return this phone and ALL the free stuff I got with it.
Thanks
Half hour of use at 95%? Cus that's not bad at all. I'm consistently getting 5-7 hours of SoT.
I think OP meant half hour of standby because im experiencing the same type of battery drain. But even with this drain im getting about 10-12 hrs of moderate use with 4.5 hrs SoT
Turn AOD off. Let the battery run down... Turn off fast charge. Fully charged the phone. Don't disable anything else. Go through a couple cycles like this. You'll see a difference. Then use package Disabler pro and disable what you don't use. You'll be happy...
So for the hell of it I turned off location in the drop down menu so see how it affects battery life. I have been off the charger for about 2.5 hours now. I have used the phone here and there throughout that time. When it came off the charger it was at 98% and it's at 91% now.
That's 7 percent with use in 2.5 hours whereas before it lost 5% in a half hour on standby with no use.
What the hell is pinging location over and over? If you hold down the location drop down menu option the phone displays the apps that use location. All of them say low battery use.
Is there a way to set these up to only use location when the app is being used?

Is fast charge bad for the battery or something? I've gone through about 3 cycles with fast charge on and battery still isn't great. Hoping it will improve after about 3-4 more cycles
All I know is that it made a huge difference for me. I think that it's more of a battery calibration thing. It really doesn't take that much longer to charge the phone with fast charge off...
