Help with Battery Life

Hi guys, I'm worried about the battery life of my HTC One.
When the phone is on lock mode, meaning screen is off, within one hour battery can go down from 1-3%. Power saver is on, brightness is auto. And 4G/LTE is on.
Also, I only play around with my settings, checking out GSAM battery monitor, within 15 minutes battery can go down 1-2%.
Now it's been 6 hours 22 minutes since I unplugged from charger, battery level is 74%.
Is it normal?
Thanks.

Gsam should be able to tell you where your battery is being used and what app. Look at what the offending app is (most likely Google maps and Google+ or facebook) and use an app like greenify to hibernate them when not in use.

Check with betterbatterystats app to see if anything is keeping it awake at

You do realize that the phone is still doing stuff when the screen is off, yes? Syncing e-mails/facebook/news stories, communicating the the network, etc. Even if the phone were completely off, lithium-ion batteries will still deplete(albeit very, very slowly) over time. 1-3% loss in an hour is pretty normal in standby. If you're really concerned about it, you can check out an app called BetterBatteryStats and it'll show you what's waking your phone up from sleep and/or preventing it from sleeping to help identify apps whos sync settings are too aggressive.
Your battery has depleted 26% in 6hrs 22minutes... you're losing roughly 4.08% per hour, at that rate it would take you ~24.5hrs to deplete the battery. Battery depletion is, can be, and should be accelerated when you're using the phone, so 1-2% within 15minutes while looking at a battery monitor... yeah. The more stuff you do with your phone, the sooner the battery will run out.
TL;DR: your battery life is fine.

Thanks for the info. However I noticed in some threads that for certain people, their HTC One can last for 1 days 9 hours. For example:

I'm guessing you're a heavy user!
What apps to you have installed? how many apps to you have?
My phone lasted 1 day and 9hrs on one charge with moderate internet use, txt messaging, phone calls - and that was without power saving mode enabled.

It's going to be very difficult for you to replicate the results of someone else(and we are lacking a ton of information from that post--is he running a custom rom, custom kernel, are screen off/on profiles being used, what apps are syncing, how often, how many, etc).
Beyond usage, phones can vary greatly from within the same model based on the manufacturing process/location/materials. For instance, there's a thread in the General Section exploring the differences in various HTC One's screen maximum screen brightness. Even down the chemistry of the batteries themselves. I know from personal experience that one of the biggest impacts on battery life can be how strong of a signal you're receiving from your carrier. If you life/work in a low signal area, the phone will increase power to the antennae to maintain the connection whereas if you're in a good signal area, it doesn't have to work as hard.

Anyone use GSAM Battery Monitor app? Why does the battery usage % doesn't add up to 100% when you add it with the remaining battery % sometime?
Yesterday it's still fine. But today my battery usage % + remaining battery % only add up to 93%.

Most people use that app. I'm not sure why it isn't working 100%. Did you plug your phone in for a very short amount of time? That might make errors. After you charge it overnight everything should be fine. Try using it for another day.

In GSAM Battery Monitor, my App Usage is always the highest contributor to battery usage, usually around 85%-90%. Screen is only 10.8%.
When I dig deeper into the App Usage, Kernel (Android OS) 23.8%, and Android System 15.7% are the top 2.

If you are referring to Facebook, email, and such, then yes Auto Sync is on. So Auto Sync is included in Kernel or Android System?

So for those who can get 5 hours+ screen on time, meaning auto sync is turned off?
Btw, do you know what is AsyncCollectorListener wakelocks that come from Maps? It also contributes to high partial wakelocks percentage most of the time.

[Q] Is HTC's built-in power saver useful?

Just as the title says is the power saver options like CPU and data connection really useful as well as the "sleep mode" option in power settings or are they making battery life worse?

If they are power savings options i don't see any reason why it would drain even more?

well according to this quote from another thread on xda in the sprint htc one forum,so I wasn't sure because it says it does make it worse.
"Power Saver mode will not save you any remarkable amount of battery unless you are maxing out the CPU or GPU (like playing games). Since what it does under the cover (besides what it advertises in the options) is downclock the CPU, this can actually be a detriment to battery life. It is better for battery life for the CPU to run at max speed for very short periods, and then go to sleep. It uses more power by running slower (and thus staying awake longer)."

Anyone?

I keep the power saver on most of the time. The main things I notice is that it dims the display (not really an issue if you work indoors) and it disables the wifi and data connections after periods of inactivity.
No real downsides (I'd be curious to hear other people's experiences). Sometimes receiving WhatsApp messages takes a couple extra minutes if the data/wifi connection goes to sleep.
Seems to give me good battery life - I average 15-18 hours, and that's including a fair amount of on-screen time and music/podcasts during the day.

I used power saver quite a bit in the 2 months after I got the phone but I don't use it anymore. In my experience it helped very little (as in added an hour or 2 maybe to overall life per charge). My baseline average battery life is 21hrs GSam tells me, and that's without power saver on at all (wifi, nfc, cellular always on and screen at 100%) and about 3hrs screen on time.
It may just be that, as was mentioned above, my use doesn't utilize the benefits of power saver because I don't often do cpu intensive things. It did run a bit cooler though. I also prevented the mode from diming the screen. I always (and still do) found that most of my power was going to the system (apps etc) @80% even with the screen maxed, and that I would lose about 20% overnight with our without power saver. So I stopped using it because : 1. It didn't improve MY USE 2. I didn't like the notification icon 3. I hear really good things about Battery Guru from experienced XDAers and the app seems more intelligent than power saver to me so I use that now. Unfortunately it's still too early to tell how much this will increase my average usage.
Regarding the issue of damaging your battery, the way it was brought up refers to the number of charge - discharge cycles a battery has. So only something that discharges the battery more quickly (so that you have to do another charge cycle more quickly) will shorten the battery's life. If nothing else, logically using power saver would not do this. It won't hurt the battery and may not hurt your usage (remember the GPU can still run at full clock for games), but I don't think it will help you much either based on my experience.

dont believe everything you see online. All it does it limit the CPU, as opposed to running 1700mhz, its capped at 1134mhz, this is not detrimental.
it takes power to make power, undervolting and downclocking processors has been repeatedly proven to assist and aid battery life.
it takes a certain balance or the two to get great results. Mind you the stock kernel is great but its adaptive. So dont be discouraged when seeing bad battery life initially.

If I leave my phone off charge overnight, I usually loose around 5%. If I turn powersaver on, I only loose 1-2%. This is with around 8-10 hours of no usage, with wifi on. It also turns off vibration feedback when using the back and home keys.
I've also noticed the phone to be slightly less responsive with power saver on. As far as I can tell, if you are concerned whether your battery will last you the few more hours you need, it will definitely help save power

It makes a difference and if you need the extra juice it will help you.
However, the amount of difference depends on your use.

If I am using Snapdragon Battery Guru should I deactivate Power Saver? Is the Power Saver a better/worse solution or a complementary one for optimising battery life?

Theoretically they should work together fine because Battery Guru studies what you do with your phone so that it can figure out what to prioritize and what to shut down - it adapts so it should adapt to the power saver situation. Underclocking the cpu shouldn't change what services it adjusts because you're still doing all the same things.
Battery Guru just finished "learning" on my phone yesterday so I don't know how good it is. But I lost 40% overnight for some reason which has never happened before. It's probably still adapting. Life seems to be better during use...
The comment above about the OS being adaptive is also very true, my first few charge cycles were dismal but they got better within a week (without power saver etc.)

Ya I'm using Juice Defender Plus on my HTC one running 4.1.2 for a few months now and I'm not sure if it's making too much of difference. Are you finding Battery Curu pretty decent?

I turned it off on my wife's HTC One. It was disabling data/wifi after several minutes inactivity, which caused FB Messenger to freak out and stay awake, which caused the battery to drain faster than if the data was just left on.

Sorry still to early to tell really, it's learning period ended yesterday so it'll take time for GSam to find the new average usage. But again it SEEMS to have improved drain during use. I'm really not sure what the drain last night was but if it happens again tonight the app is gone...

I used to have a higher drain, but after some research, I found out using betterbatterystats that google maps was waking up the phone often and preventing sleep. I corrected this by disabling "report from this device" in google maps settings.
Before this, I experienced similar battery drain with power saver on.
From experience, it's best to determine phone sleep time and app battery usage, and correct this to achieve the best life.
I'm currently able to get two days with light usage without power saver!

I changed my mind, I'm consistently losing 40% per night after Battery Guru activated. I can't confirm that this app is the problem, but it's never happened before and I haven't changed anything but adding the app. Maybe just me experience though.

I've uninstalled BatteryGuru for the same reason

I'm relatively certain that for many people this is super old news, but I'd like to share this anyway just in case it helps anyone (and a bit because I'm just so impressed by how it works )
I've tried a few different power saving strategies on this phone and have been disappointed with all, including just keeping power saver on all the time. I would always lose 20-40% overnight no matter what I did. I should also clarify that it is not acceptable for me to just disable a bunch of things to get that drain under control. So one day I turned on power saver (everything checked off) and just turned off wifi, and I've been doing it ever since because now I only lose 5-10% over night maybe a strange thing to be excited about considering my other devices lose as little as 1% in that time with nothing turned off, but everything's relative.
I think now I'll try keeping wifi off and power saver on throughout the day and see what I get. Though I'm not sure I like the thought of data being turned off during the day when the screen isn't on...
For me at least this is the single best battery saving thing I've ever done on my One.

What you mean by saying that you "turned on power saver (everything checked off)"? What Power Saver does if everything is checked off? I suppose like that it actually doing nothing. If you uncheck everything and turn it on isn't the same as turning Power Saver off?

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 Sony Xperia Z5'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!

Battery drain rating on Sony's Stock ROM is only average (0.7-1% per hour in Airplane Mode), no matter if (unrooted) Stock ROM or with Custom Kernel; 0.5% at best with gauge tweaks and other modifications;
AOSP/CM ROM appears to be excellent - 1% per several hours;
doesn't come close to my Note 3 (a few per cents per day) or even my Galaxy S1 with the original battery (2-3% per day), but that's no disadvantage of the Z5 per se
battery's technology simply wasn't allowed to catch up with progress yet

Something keeps my device awaken - not sure what this could be, as the Wakelock Detector and other apps that can show culprits require root to run on Android versions from KitKat and above. This causes battery drain when the phone is not in use overnight. Does anyone else have similiar issue?

it's most likely something else
or part of the kernel or deep within the system,
because blocking wakelocks does hardly have any effect

I find my standby drain to be terrible. I can leave my phone in my pocket, with all background app closed down and it still somehow looses 30% in about an hour.

You keep breathing while sleeping

I use GSAM Battery Monitor to keep an eye on things. After a few weeks I'm happy enough with battery drain levels.
It mostly depends on phone signal; if I'm at home the signal is very weak and this can drive the standby drain up to nearly 10% an hour, and the phone can get warm. But if it has better phone signal then the drain can be as low as 2% or 3% per hour.
I have my phone set to turn off wifi when screen is off. I also use a Notification area weather app, Messenger, WhatsApp, Facebook, Instagram, etc and I have a number of email accounts and calendars syncing regularly so I would say I'm not running things in a lean manner. I'm sure if I uninstalled most of these apps my standby time would be spectacular, but then I wouldn't be getting particularly good use out of my smartphone.

Have you tried with BREVENT APP together with an aggresive Doze app (Greenify, ForceDoze, NaptimeX)? I´ve now installed Brevent + Greenify and standby during night from 100% "only" takes me 0,5% per hour more or less.
Also inside Brevent you have possibility to access to AppOps (be careful with this option).

I found that Bluetooth was causing massive drain on my phone. The fix which worked for me without turning off bluetooth (I like it to auto connect when I get in the car) was Settings->Location, then click the 3 dots menu in the top right and then Scanning, turn off Bluetooth Scanning. There are a few other things you can do as well.

whenever the battery is less than 60% , I get notifications with a huge delay or I don`t even get them. Especially the messenger app. How do i keep the auto-sync always on gmail regardless of the level of the battery , and also to be on when it`s on saving mode?

It just automates the regular "Power Saving Mode" at night while you sleep. Nothing special.

How useless.
I'd rather have a real battery guardian app that lets you limit charging to a desired level, enable bypass charging, and enable very slow charging at night.
These bloody things should let you limit charging to a desired level, enable bypass charging, and enable very slow charging at night.
For example, I have a 5W, 2.5W, and 1-2W charger which claim to need ~3 Hours, ~6 Hours, and ~8 Hours respectively to reach from 40% to 100%. I'd love to be able to directly enable this charging rates.
There's no reason why your battery should hit 100% within 1-2 hours of sleeping. That'll lead to the phone facing at least 6 hours of 100%-voltage battery-level damage daily for years on end.
Apple solved this in their own way by predicting when the user generally needs the battery at 100% by, until then they only charge to 80%.
Android should've had some built-in functionality to control this charging behavior. But, alas, they do not care about our phones. We're not even asking for predictions/AI on when to charge to 100%. We just want basic control.
SONY XPeria allows near-perfect granular control over this.
We're trying to petition Samsung to change their behavior on this.
If you can do so, then, charging 37-65% or 35-65% would be ideal and result in the least amount of damage relative to usability, IMO. Then again, I'm almost always near a charger or worst-case scenario I'm near a power bank.
