Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?

I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.

Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.

This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.

I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU

This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though

when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.

Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.

Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....

Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.

i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.

If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).

W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....

What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.

At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

battery life

anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.

See my post here:

Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.

I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.

Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.

Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.
Sent from my HTC Glacier using XDA App

I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.

I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.

I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.

My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.

I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.

I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.

heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life

Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.

It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu

cell standby or phone idle?

I did a battery wipe in cwm and my battery life went up a lot. for two days I got like 22hours on normal use, 4g, Wi-Fi, you tube, music, etc. this morning my battery status was at 80% showing cell standby and phone idle. should it be either standby or idle for overnight? if there are no app running? there was nothing else running, is it normal for both standby and idle to show for the overnight?
thank you

Cell standby is battery used by the radio.
Phone idle is battery used when phone is idle.
Pretty much even if you're not using your phone it will still give out signals back and forth (thats how you get text/calls) unless you turn it off completely. Phone idle would be how much battery it uses while its on idle but it also goes based on the time. So if say you get about 1% battery/hr idle, and you never used your phone for 4 days but now you're out of battery, your stats would be 100% Phone idle because the idle is what used the battery. If you play a game that uses 2%/hr it will factor in with the percentage with everything else of how much power its using. Example say i lost 5% battery within an hour and 2% of that is from idling and 3% was from a game etc...
So when you're sleeping and the phone at anytime access a connection (text/fb notification/updates/sync) it will be on your cell standby.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the OnePlus 6T's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

10% drop in 8 hours in this video:
https://www.youtube.com/watch?v=ZgtpvkGRr4k
Can anyone confirm? Does standby suck?

Sleeps well. I'm 21 hours and at 65% off charger. 2.7 hours screen on time.
Deep sleep cpu speed is 76%
Make sure you don't have things eating your battery with screen off

My standby has been great. Usually 5-8 percent drop in a 5-7 hour window. Way better than my V30; that thing would eat up 15-20% every night.

Mine has been at 3% drop per 7 hours I'm asleep. I don't know if it has anything to do with DND being on but I was also getting the same drop with my P2XL.

I have been noticing this everyday for the past week. And almost every single time I see about 4-5% drain in about 8-9 hours which is pretty good.
This is on WiFi. So if you're on mobile data there might be a slightly higher drain.

Current status: In deep sleep for 86% of screen off time.
I've also noticed 4-5% drain in about 8-9 hours on WiFi and DND. I'm happy.

Only lost 3% overnight, including picking the phone up and using it a few times.

Not on wifi mine went from ~40% to 3% also my alarm didn't go off. Alarm was set at 545 woke up at 630 and when I picked up my phone to check the time that's when the alarm decided to go off. Nice feature ignoring alarms to save battery.

Is it good enough?

My battery stats are messed up. Battery % goes up even when I'm not charging.

How long have you been using your phone and what's the lowest battery percentage you've hit?
Sometimes it helps to let the software recalibrate the battery by charging the phone to 100 and going all the way down to 0 and then charging back to 100.

I generally lose about 1% every 2 hours overnight. About 1% every hour in the day (When wake my phone up every now and then)

Is it one plus 6t bro?......actually last night my screen on time is 8 hr 17min or smthing.......bt not this much like urs .......what features u disabled to save the battery?

Light use on this thing is crazy. And by light use I mean still using it for over 2 hours a day I can still eek out 2 days without charging.

I'm really unhappy with my battery drain. I see about 2% per hour when I set the phone down and sleep.
I have a Gear S3 paired, two sim cards, and email notifications for about 8 email accounts. But other phones I've had would drain 1% or less per hour under the same conditions.

On the new update they improved the standby drain drastically

My post was made from the new update. I haven't noticed a difference at all.

That's a lot of drain right there. What other phones drained less with 8 accounts syncing and a paired watch?

Mine also has worsen with the new update, and the fingerprint sensor also got slower than the previous build.

Battery life in airplane mode?

I ran an experiment during the weekend, the phone was completely disconnected for 3 days. After the first day I even enabled battery saver. I don't have AOD or any other running apps. After 3 days it lost about 30% without any usage, quite linearly. This seems kind of high, I could notice the same drain in real-life and blamed it on poor network reception. I get perhaps 1-2% per hour inside the house with WiFi connected and nothing else running. Does this sound normal or should I try resetting the phone?
As a dumb comparison, I took the iPhone SE (old one) out for a day, connected to 4G, WiFi on, made a few photos and after a few hours the battery was still at 100%. Even if it's really only 95%, the P3 would have been already at 90% with twice the battery size.
