Hi guys, any thoughts regarding Battery life? I get roughly 8 hrs, not the 9.5-10hrs advertised/reported in the forums. Of course, this is with very high use, screen on 7.5hrs, wifi on the whole time, plex on for an hour or so, mobo video playing for an hour, and web browsing for a couple of hours, and some games too. Is this standard? Dock battery is ok, gives around 5 hrs. Any ideas on improving battery? Screen stays at 60% brightness all the time. Plus i have cnn, facebook, youtube, pulse, cnbc and plume widgets on. And active mail sync in the background.

The 9.5h time is stated for constant 720p playback so I don't think your usage is that much higher. I never stopped the time for my ASUS but I am happy with it and I guess that's what matters most.
I use SetCPU (requires root) to set the clock speed to 216MHz when idle. That seems to improve battery life.
I am not getting anywhere close to 9 hours. At first I thought it's the apps I have been running in the background or the brightness, but it's the same after I adjust it. I get about 6 hours.
Dude....6 hours is pretty low.anyways, i havent rooted it yet because of the impending otas.will do it as soon as a gr8 custom rom comes out.

Yes but i do video streaming over wifi. Also my wifi is on the whole time. And as far as i know, wifi takes more battery than video decoding.

The 9.5 hours is for
Airplane mode
playing a local movie, only
display at about 30% based on the NITS listed and Anandtech measured brightness
I bet you can achieve the same if you duplicate their testing scenario.
As for improving battery life decreasing screen brightness can have a huge difference. The screen is often the #1 power usage item when I check on my phone. Also, reduce the checking frequency of any task that needs Wifi to get data.
It's been 15 days now since I had the TF and I can tell you based on my usage - I used up;
12% per hour - airplane mode, play games watch movies in auto brightness
1% per 2.5 hours standby.
So more or less 9 hours usage should be achievable.
I get about 18 hours of constant use with dock
I play with the thing all the time and I honestly haven't ended a day with my battery being below 50% yet.
Actually, out of fairly constant use, I haven't charged mine for, let's see... 2 days, 6 hours, and 52 minutes. Currently at 48% charge.
EDIT: Oh, and I don't have the dock, so it's not counting that.

It stays on auto. When it lasts me multiple days, I can't say I really worry about saving battery much.
For example, I unplugged it this morning at 7, played with it quite a bit today including playing Zenonia for a little over an hour and letting my friends play around, and my battery is currently at 75%.
Hi all. I just wanted to chime in on this thread here. Im a former owner of a xoom and can say that tablet was a beast when it came to battery life. I could have a full charge last for 2 weeks+ with very minimal use all consumed by idle standby. That was something to be said. The tf isn't as good; I can tell already, but I was surprised today! I charged it overnight and unplugged it around 11am. 98%, until I woke it up right now! Its at 97% with 13 hrs 39min. I probably had the screen on for only 5 minutes, but pretty good! One thing to point out that helped me a lot was to always have the tab in airplane mode. You can still have the wifi on and stay in airplane mode. That seemed to make a difference with the xoom. Just my $.02

I get 5ma constant use in sleep mode. By that logic, u would lose 1% in 13 hours on sleep mode. So yeah, idle use is pretty good. Decent tested flight mode yet though.but seriously, y doesn't battery use show the percent divisions like my phone? :O

Its doesn't seem that any of you guys are reading the manual when it comes to battery.
It says it clear in the manual. Why not follow what the book says, I guess some dont read.
"If you intend to use battery power, be sure to fully charge your battery pack before going on long trips.Remember that the power adapter charges the battery pack as long as its plugged into the computer and AC power source. Be aware thats it takes much longer the charge the battery pack and when the Eee Pad is in use"
Remember to fully charge the battery (8 hours or more) before the first use and whenever it is depleted to prolong battery life. The battery reaaches it's maximum capacity after a few full charging and discharging cycles.
"To prolong Battery life, charge the battery for up to 8 hours when using Eee Pad for the first time and whenever the battery power is fully depleted.
I recently installed CoreDroid 6.7 and along w/ changing up some settings and using SetCPU, I'm getting unreal battery life. Yesterday I took my phone off the charger at 1pm and with normal everyday use along w/ naviagation, email, facebook, and browsing I woke up this morning around 8am and still had around 50% battery life. I charged it before work and took it off charger at around 11am and as of 5pm I still have 75% battery. Who needs an extra battery or even a bigger one when you can get these results w/ a ROM and SetCPU.
I bet honeysense+setcpu+honeysense UV mod beats that by a few more hours

I get about 5 hours battery on heavy usage. WiFi on, setcpu 1.2ghz, playing a game or watching movies on vplayer.
I got 4pm-9pm from full charge to 15% yesterday with mobile data on/off, fm radio/HTC music player and light texting. No gps or WiFi.
I have no idea what radio I'm using, Android revoultion 5.1.7
I got my HTC One Mini yesterday and I'm getting pretty good battery life so far, how is it for you guys?
I'm using jmz's Stock Rooted Odex WWE Rom and Jmz M4 Kernel 9-04-13. I unplugged my phone around 9 AM this morning and it's now 1:45 AM and I'm at 48%.
I installed 12 apps, torrented a 315MB file using uTorrent @ about 600 kb/s, watched 23 minutes of 720p video using MX Player with hardware decoding, watched about 15 minutes of YouTube videos, went on Facebook for about 20 minutes, browsed the internet for about 5 minutes, browsed a forum using Tapatalk for about 15 minutes, made about 5 minutes of calls, sent/received about 20 texts, read a manga chapter, used it as a flashlight for about a minute, used it as a remote for XBMC for about 2 hours, flashed a kernel, and took a couple of pictures, a 30 second 1080p video, and a Zoe to test out the Camera. All of this was over Wi-Fi.
I think I could easily get 2 days out of the battery as my typical usage would be lighter. How is the battery life for you and what Rom/Kernal are you using?
Stock UK Vodafone Rom recently updated with the it's package.
Well...I am sadly unimpressed by the battery. I've had mine now for just under a month and don't get a day.
I use it to surf the BBC website (in mobile mode) over 3g and at other tines WiFi.
I make calls about 30-60mins a day and play a version of bubble breaker.
I can literally see the power drain when surfing the web. This us the single most draining activity...much worse than when I used my desire.
I have configured all power save options, disabled all non essential apps, and ensured the phone is not burning background or unnecessary apps.
Still it goes rapidly. It's a shame but I like the phone so will live with it.
2 days...yes if all you do is make calls. Anything more demanding not a chance I'm afraid. I have tried, a lot.
So it is now 1.10pm and I have 52% and at 9 am I had 100%. No video no gaming but a mix of BBC on WiFi and 3g (i have a femtocell so no burning power while looking for a signal).
Nice phone in so many ways but battery life, in call quality and control, are very poor.
All the best,
Sam
I am planning to buy HTC one mini, Wanted to get real idea of battery life, so this was helpful. Could you laso tell me if that 1GB RAM is a problem maybe once you have 60-70 apps ? I thinking of 2 years life at least so was concerned?

For me it isn't too much of an issue, but they really should have equipped it with 2 GB of memory, 1 GB has been the standard for about 2 years. I have 42 user apps installed and most of the time I can have multiple apps open without any slow downs. Occasionally if I have multiple heavy apps running (Maps, Facebook, Pandora, Chrome ect.) it can slow down due to the lack of memory, but if I close one it speeds right back up. If you read any reviews you'll hear something along the lines of it's stupid that they only gave this phone 1GB of memory, but for most people it won't be a problem which I agree with. I'd suggest trying it out at a local store before buying it. Different people will see things differently, to some the HTC One Mini and S4 Mini will seem slow compared to the regular One and the S4, to others it will seem very fast.
ok guys please keep in mind that your mobile connection eats your power rly ****ing bad. I did a lot of tests with the mini and i'm was even able to get 5days with 25% left. Camera or wachting videos coast a lot of power as well but music is ok that does not need that much power.
Its all about your connections and how good the signal is, so if you want a longer battery life only use wifi.
The device has smaller screen size, lower resolution, half the number of cores, lower clock speed, lower powered GPU, half the RAM, no NFC or OIS. It should get *better* battery life than the full-sized one all things considered, though the smaller battery will definitely even this out somewhat. I wouldn't be surprised if under typical moderate-high usage involving CPU and screen this device should hold out similarly to the HTC One but in standby, etc it will be a bit lower.
Notebookcheck and GSMArena have done thorough battery testing, though notebookcheck doesn't test standby time and GSMArena's standby time testing method is a bit suspect.
Anandtech haven't published a review of the Mini yet but in their review of the Galaxy Note 3 you can see some battery tests they did of the HTC One Mini and it holds out pretty well considering it's not a phablet.
I bought mine two weeks ago. On the first week, my battery just last 10 hours at least and after a few days of experimentation of various settings and process monitoring, I can last 24 hours with still 20% remaining.
My daily usage can be define as quite conservative as I'm busy at work most of the day.
Here's my activities to give you an idea:
Call - at least 3 minutes a day
SMS - least 20 messages a day
browsing via HSPA / 3G - at least 1 hour a day
browsing via wifi - at least 1 hour a day
playing games - at least 30 minutes a day
reading / composing / sending emails - I set this to manual, at least 5 times a day (when I'm at home)

No matter what the phone, you tend to see battery life tests showing 8+ hours of web browsing battery life. However, real life never matches up to this expectation, with 3 or 4 hours of web browsing much more typical. This is the case with all smartphones - even a device like the Note 2 or Note 3 (albeit with higher expectations to begin with: - a Note 2/3 may tests 11+ hours web browsing but typically get 4.5+ in real-life conditions).
Unfortunately this leads many to believe that their brand new device (or its battery) is faulty. But in most cases this is not true.
I'll attempt to explain the real reason for the discrepancy.
Most importantly, the battery life tests are exclusively limited to that activity or task. For example, fully charging the smartphone, continuously web browsing for 8+ hours until the phone dies. In reality when we use our phones, the phone will be on standby, or doing other tasks, at other times. For example, 8+ hours of web browsing from a full charge is not the same as getting 8+ hours of web browsing over a 16 hour day. Those other 8 hours, even if the phone are on standby, are going to use up some of your battery, too.
The single biggest battery drain of a device is usually going to be the screen, unless you have specifically forced the screen brightness to a low (<33%) amount. At full brightness, a smartphone may burn through battery after only 3.5 hours of web browsing even if it could last 8+ hours at 40% screen brightness (the brightness control is not usually linear in terms of power draw). Review sites tend to standardise on a particular brightness level that is relatively low (the reason for this is often that allows fair comparison with devices that just can't get as bright). The bottom line is that 8+ hours of screen on time at lowish brightness might drop to half that or lower if you let auto-brightness bring up the brightness during the daylight hours or when outdoors, or if you prefer higher brightnesses.
Often, battery life tests will be done over wifi with mobile phone reception disabled entirely. This is not realistic as with a smartphone you're usually connected to a cell tower even while you're using wifi, so that voice calls and texts can still come through. Also, cellular uses a lot more energy while idle than wifi does. So even if you set the brightness really low and do nothing else with the phone, you still shouldn't be surprised that you can't get 8+ hours of web browsing if you also have the phone connected to a cell tower in the background. Some sites will conduct battery life tests over the cellular network instead of wifi, and typically these will get much lower battery life ratings (eg. 4+ hours, even with the same brightness level as for the wifi test).
Bottom line is, don't head back to the shop if you only get 3 to 4 hours screen on time during the day with web browsing. This is entirely normal for *some* usage patterns. You can improve it by:
Disable auto-brightness and set the brightness to a low-ish value, say 30%-40% of maximum. This might be able to double your screen-on time compared to full brightness.
Avoid using the phone much in direct sunlight. For the brightness to be high enough to read in direct sunlight, you'll be burning through your battery quickly, and if you've set the brightness manually to a low level as advised above, you won't be able to read it in direct sunlight.
Connect to wifi (but of course, only if you trust the wifi network to be secure and respect your privacy).
Realise that if you ever play CPU- or GPU-intensive games (most casual games shouldn't fit in this category) then a beefier battery or external battery booster may be a good investment. There's not much you can do about their battery use.
Only after considering the above should you hunt through battery usage analysers and wakelock detectors. In many cases even a misbehaving wakelock that keeps your phone partially awake all day has a low impact compared to having the screen on full brightness for just 20 or 30 minutes.
how's your battery doing guys when you go heavy use with this phone ? with or without wifi.
My battery is doing well, thanks for asking

before i rooted i had great battery life. Unless your playing games for a while with the screen on full brightness. I saw about a day to a day and 1/2
Rooting alone does not make a bit of differences to your battery life
Um y'all know that rooting has nothing to do with battery life, right?

My battery life increased 10 fold after jailbaking my phone...
I get 4 hours screen on time with average use
Total on-time varies with what I do. Could be 10 hours could be over 24
I'm usually listening to music, texting, playing the DS emulator, browsing, or just social media

so anyone ever reached the phone from fully charged with standard SOT 3-4 hours from your nexus 5 and the battery still runs good ?
For me the key about the N5 battery life is two fold;
1. It loses very little juice on idle, even with all of the radios on.
2. It charges exceptionally fast.
Now, if you run screen brightness up and use google navigation the battery can go fast. Real fast. But for me, what is important is that if I know I am going to be away from the charger for a while I can easily tweak my behavior to get me there.

Hello,
I have a problem with my Nvidia Shield K1 tablet
Running system: Lollipop 5.1.1 (downgraded from 6.0.1)
ROM: Carbon 5.1.1-UNOFFICIAL-20160809-1925
Kernel: from the above rom
I've brought this tablet as used and it works very well and smooth,
but when i just want to browse the web, watch some youtube videos or play some emulator games
i can see the battery draining very quickly, with simple web browsing and youtube my battery is draining with continuous use in like 4-6 hours (100% to 0%),
my question is is this normal?
1 time when i used some battery info apps from the playstore it once stated that my battery condition was "bad" when i had like 5% charge left, but never saw this again.
I've also tried to disable 1 core so it will run on 3 cores, down clock both cpu and gpu by a couple hundred Mhz with Kernel adiuator but somehow the settings jump up and down.
This battery drain is on marshmallow, and lollipop both on stock and custom roms, even after restoring stock rom.
Can someone say what is a normal battery duration with continuous use of the tablet? a rough estimate will do, i'm just wondering if my battery is defect or something,
also overnight it will drain like 7-8% if not used, i dont know if that's normal too.
Or can someone help me with this issue or a way to pinpoint the issue?
P.S. i've also applied multiple doze applications like Greenify and disabled most of my start up applications at boot, battery stats don't see any unusual wake locks either.
Thanks in advance for the replies and help.
First of all, it depends on the brightness of the screen. The higher the brighteness level the higher the battery usage. Second, if you play games or stream HD videos 4 to 6 hours is normal. Just browsing the web, word processing and office work should give you easily +9 hours.
Did you deactivate **Adaptive brightness** under **Display**?
Because no matter the ambient lighting, it's always too bright! Manually is the way to go.
Last but not least, is **app optimization** off? If not, do so. It only slows down the performance and drains battery.

Thank you for your response, and yes i have my brightness on manual as overday i like it at around 60-70% brightness and at evening/night i use 5% with a screen filter app to darken it even more which i like for my eyes.
I play emulator games sometimes but if i do i wont get 4 to 6 hours i can get around 2 to 4 hours max, as with browsing the web and office related stuff i have never seen it getting 9+ hours, the max i would get and i tested it several times was around 6-7 hours max, do you have any idea why this is?
I haven't tried disabling "app optimization" but i will sure try to disable that option and hope for more battery life
Could it also be that my battery is worn out/kinda dead as i've bought this tablet second-hand and not new?
+60% brightness that's something. My brightness level usually won't pass the WiFi symbol at daytime and when I game. So it's something like maxi 20% to 30%. And at nighttime and dim indoor lighting it's on 0%. I've to assume that's why I get more on screen time.
Haha, I'm used to darkness.
Either way, I highly recommend a 10k powerbank to double the time.
Moreover, WiFi takes a lot more battery than the Nvidia battery stats show! Just tally up the percentages, and it'll never add up.
The other day, I was streaming HD vids, playing some games, browsing the web and after +5 hours my battery was at 5%.
Most days, I work offline and I get way more on screen time.
