[Q] Is HTC's built-in power saver useful? - One (M7) Q&A, Help & Troubleshooting

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.
Sent from my HTC One using xda app-developers app

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?

Bad battery after update

Is anyone else having bad battery life after the update? Cell Standby and Phone Idle used to draw most of the power before the update, now they're low on the list however Android OS is eating all the juice now. Android OS gets up to almost 70% usage overnight and the battery drains a good 30% or more just sitting idle for 6 hours.
I installed a program called watch dog and it's telling me that "Base System" seems to be the culprit with lots of CPU use, particularly when the phone is idle. I've tried a variety of things like uninstalling recent apps I downloaded, disabling the 4G and 3G radios, trying airplane mode, changing settings, etc. and nothing has made a difference. Really want to avoid trying resetting to factory default.
Have you tried recalibrating the battery or tried bump charging?
Sent from my SCH-I510 using XDA App
Since I use my nav dock in my truck to stream Pandora over my stereo, it gets charged several times a day; however, Android OS is now my big drain as well, where it used to be idle or screen using the most. Since unplugging exactly two hours ago, it has drained down to 70% on the stock battery. (I only use my extended battery when I will be away from a charger for a long time. Makes the phone too thick for my pocket to be comfortable.)
On a seperate note, Google Voice now hangs my screen as well when listening to voicemail. Hey, at least I don't get the random reboots and power ups... :what:
Sent from my Xoom using Tapatalk
I doubt calibrating will fix the issue because I don't think that's the problem. A system process appears to be hanging and causing the CPU to run constantly. Maybe a bad update install?
Either way I used to get much better battery life before the update. Never had any of the random reboots or many issues with data like others.
My battery life seems somewhat worse after the update. Everything else seems somewhat improved.
My battery seems about the same if not slightly better after the update.
I do a few things to conserve battery which really conserve the battery.
1. 4G off unless I need it.
2. Battery mode set to 'maximum battery saver'.
3. WiFi sleep policy: When screen turns off (although I think the maximum battery saver will turn it off automatically)
4. Display brightness: 0% unless I need it.

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.

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.

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.

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.

New Z3C - Battery dissapointing

I just bought my Z3C a couple of days ago. First thing I did was charge it fully and then I started using it. It went from 100 to 0% in about 21 hours. During that time a SIM card was inserted only during the last couple of hours, but I did use the phone fairly often. The attached thumbnails show the details.
I did notice that it almost loses no charge in standby. But today I noticed an increased decline during screen on time after standby time. See last screenshot attached.
I expected more from this battery based on reviews and Sony's claims. Is this normal or is my battery faulty? While some here report similar numbers, others seems to get a lot more out of their batteries.

You shouldn't expect more from this battery based on reviews, you should just look at what some people got out of their phones.
Give the phone some time to settle in. And don't forget that it's almost summer for us now, more sun means using the screen at a higher brightness so that will also have some impact on your battery life.
Look what kind of useless apps are running in the background and stop them and don't worry about the estimate, it really doesn't mean much. Right now my estimate is 9 days, because I barely touched my phone.
I really don't believe in such a thing as faulty battery. Charge your phone, restart it and see how it reacts then.
Is Stamina mode enabled? If not, then what you have is typical. Getting a full day out of one charge is about all you can expect from a smartphone without some form of battery saving measures enabled.

Here are my results:
http://forum.xda-developers.com/showpost.php?p=59933232&postcount=48
At the moment I have 3d 10h battery life and still 40% left. Tomorrow after work @ 12 our time I'll charge my phone again, so that's almost 5 days.
(But that's with a lot of idle time)
(Vergeet geen apps te freezen en je telefoon te restarten)
With moderate usage, you should generally expect just about 2 full days of battery life from this phone. And that is with Stamina mode enabled to help the phone sleep when the screen is off. However, this is not accounting for any extreme measures some people take to extend their battery life (e.g. disabling background data/sync). Once you remove these features, you're no longer using the smartphone as it was intended, so it's not a fair comparison.
I can easily get 2 days out of my Z3C before I think about charging it. And I've never used Stamina Mode.
I guess I could install some app to monitor battery usage and stats but I'm not that bothered tbh.
We all manage a variation on the smartphone thing, in terms of data, wifi, gaming, emails, browsing, texts, calls, etc, and its slightly different, in terms of use, from one user to another.
I'd echo the sentiments of another user who said give your battery time to settle in. Give it a full charge, discharge cycle a couple of times, and don't worry too much about it!
Peace.
Thanks for your feedback, guys. I'm currently fully charging and discharging my battery. Several cycles complete.
The best result I've gotten so far is a little under two days with moderate usage and thorough measures to increase battery life. I turn on airplane mode when I go to sleep. Stamina mode is also enabled, but only the reduced performance part. I'm also using 2battery, which turns off WiFi and data when phone is in standby, and turns them back on briefly every 15 minutes. (While I agree that turning off data connections defeats the purpose of a smartphone, I also believe that there is no need for a constant connection when I'm not using my phone. 2battery achieves that. Although I must say it doesn't seem to kick in a lot on lollipop.)
So despite these measures my battery seems weak compared to yours. Anyway, I'll be taking your advice and I'll give it some more time.

You need to be rooted tho (Which shouldn't be a problem)
Are you using GPS or is it always on?
Your battery is fine. You probably lost some standby life when you put a SIM in it, as that would cause your cell radios to begin seeking your carrier's towers.
Do activate Stamina mode if you haven't already done so.

Well yeah of course GPS uses a lot, especially when you don't use it, it's just wasted energy so to speak.
Greenify lets apps go to sleep earlier/faster so that they can cause less wakelocks.
With Greenify and DS BS I don't need Stamina mode and many of us are even wondering if Stamina is working most of the times, these two apps I'm certain that they work.

Well, I've been keeping an eye on it for the past week, and I seem to be losing next to no charge when screen is off. My phone is in deep sleep over 75% of the time. (According to Better Battery Stats)
I do seem to be losing 1% charge for every 3 minutes or so while my screen is on. Is that normal? We're not talking gaming or anything demanding, just some browsing and messaging.

I think the best way to measure if it's correct or not, to for example put some movies on your phone and let them play constantly, see how long your phone can manage.
You should get at least 6 hours of on screen time using that method
It's too late to say this, but after getting a new battery/phone you should always drain it fully and then fully charge the battery so that the battery has a proper charge (it saves a lot of battery capacity and battery life)

Good that it's too late, because it's incorrect. This suggestion dates back to the days of NiCd batteries which had "memory effect". Li-Ion batteries found in modern devices for at least the last several years and definitely since the beginning of Android don't have this effect, but have something else - when you drain the battery completely, you cause damage to the battery cells, and it can withstand only a few of these full-draining cycles before losing significant part of its charge capacity. This is why both laptops and phones have protective measures to turn off the phone completely before the battery reaches a dangerous drained state. And as the batteries go bad and their "low percentage" scale becomes unreliable (not able to sustain operation currents with low charge), these protective mechanisms can fire too late - which in turn can cause storage corruption to occur, if the power is lost gradually and not abruptly during operation.
To another poster that doesn't believe in faulty batteries - he better should. Batteries go bad with time and charge-discharge cycles, they're harmed by complete discharge, and can go bad in several other ways. However, I wouldn't expect a battery to start its life damaged - quality control of the manufacturer should prevent this.
My results for reference - I have ~2-3 hours a day SOT, 1-2 hours tethering, have several phone calls, messages and mails - and the phone is usually upwards of %50 at the evening. I have to run it through ~4 hours navigation to reduce it to sub-20% towards the end of the day, and actually see no reason why a smartphone should hold any longer - it's routinely recharged every night. The main problem for smartphones, to me, is not surviving till the end of the day.

Thank you for sharing, but that advice is about as outdated and useless as changing your car's oil every 3000 miles. Batteries simply don't work that way anymore and some studies show that battery life is actually reduced when you perform full charge cycles instead of shorter recharges throughout the day.
Edit: looks like someone else best me to it :-/

Actually sorry to break it to you, but you are wrong, Li-ION batteries do have a memory effect, since about 2013, researchers have found that they do have memory effect.

Well, thanks for showing me something new. However, this is a very different effect from NiCD. While in NiCD this effect would prevent the battery from taking a full charge when repeatedly not discharged fully, in the research you've showed there are 2 very important points:
1. What matters is not the discharge, but rather a charge. Charging not fully is a way to trigger this effect. On the other hand, discharging partially (like in NiCD) doesn't trigger it. This point makes the info, while indeed interesting by itself, irrelevant to the current discussion, and keeps your previous suggestion wrong and bad for the battery.
2. If kept charging a bit longer - the battery would still charge fully, though it would take a different amount of time from the expected. For night time charging, when the phone is connected to the charger for several hours more than it's needed to actually regain the charge, I'd guess that most of the time it does the job of filling the battery properly even after an incomplete charging cycle.
[edit]
After reading it again - actually there is a third point that makes your suggestion even much worse than I thought it is:
This memory effect that you've pointed to is triggered by having an incomplete charge followed by a complete discharge. That means, incomplete charge with incomplete discharge don't cause it - a complete discharge is required. And when you receive a new phone, the battery isn't fully charged - so if someone goes by your suggestion:

He would actually be triggering the memory effect you've linked to, on its bad side!
And just for reference, here is a recent article from 2015 that is far less technical, but does a great job of explaining battery behavior in practical terms that average people can understand:

Bad Battery Life?

Hey guys, I've seen posts about people getting amazing battery life, both on stock and on a custom rom. I can never seem to get the same results, whatever I do. Sometimes, I'll toggle a setting and I'll see improvements for a day or two, then it goes back. Even more frustrating is there have been times when I turn the setting back to what it was and see improvements. It was like this for a while, but recently I've kinda gotten stuck with ~15 hours from 100% to 10% and nothing seems to change it. I have location on device only (its for weather, battery saving seems to be worse because Google services just syncs all the time and eats battery) and mobile data on. I've disabled pretty much every Verizon app and I just use moto display and the sleep thing. What else can I do to get better battery life short of a custom rom? The only reason I won't do a custom rom is because my parents won't let me spend $25 on sunshine, whether it's their money or mine.

I exactly get the same results as you. I'm on stock and disabled all verizon apps. A help could be really nice.
Keep in mind that battery life varies GREATLY upon usage. I can kill my battery in a matter of a few hours or have it last for nearly a week. Sync frequency, sleep time, connectivity, refresh settings, screen brightness, CPU usage, vibration on/off, number of wake locks...I can go on and on.
For example, I had my S4 last 5 days before it dropped to 80%, as you can imagine I didn't use it much. However, that same phone died in probably 3-4 hours on me also.
What matters most is if you have more battery life than your previous phone. Never compare your battery life to others.

I included some usage statistics in the ingur link. A lot of battery seems to be used by Android os and android system. Is there anything I can do to lower this?

What do you have your screen brightness set to? Your phone looks completely normal in terms of battery usage (Android/Google will always use a couple percentage).
Try turning off adaptive brightness and putting your device to the lowest brightness you can stand, that should add at least another hour or two depending on your current settings. 3 hours of SoT over a days usage with what looks like moderate use (YouTube, Messaging, etc.) isn't too bad for this phone.

Thanks for the advice! I guess I was expecting too much out of this phone Oh well, i'll just wait until i can get $25 in amazon or google play gift cards to pay for sunshine so i can get computerfreak's rom.
I am on CF's latest ROM and I'll say my battery life improved compared to stock, but not by much. I may get 6 hours SoT but my battery is down below 20% by the end of the day, and that is if I avoid playing games. Playing games all bets are off, the battery runs out quick.
There are some out there saying they get 8+ hours SoT and 48+ hours between charges. I call BS on that unless you are running minimum brightness and not doing any syncing or anything location based, and possibly even turning off cell data. Showing off with pictures of their battery stats and not telling the whole story.

If you unlock with Sunshine and install RR, you can use the custom kernel to tweak the CPU and GPU frequency to save battery life.
Additionally, there are other ways to save battery, like adjusting the pixel density and colors. (At least I think so?)
Greenify also helps. I think that is available for non-root as well.
Also, check your wake time. If always awake, could be the Google services running constantly trying to update.
There is an app to fix that, but I think it requires root.

also, my phone really likes to shut off before it reaches 0% battery. Is this normal?

I doubt its normal, buy I have noticed that mine does that too. It usually shuts down around 7% without warning.

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 BLU R1 HD'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!
Good very small drop while not being used, even when loaded up with apps.
I experience pretty bad battery drain on idle. Basically, if I leave my phone alone without turning on the screen, it would be fully drained in about 30 hours.
I've reset the phone many times but phone idle always remain as the top battery draining app. averaging about 100 mah per hour constantly.

Exactly this! My phone uses more battery while on standby than with the screen on watching things! I don't understand this behavior. Powernap + Greenify + Amplify doesn't solve it either, even the things that keep it "awake" are hibernated and also delayed by Amplify. Wakelock detector doesn't even detect any apps that are running during standby either. Also, I have no bad signal because it is always on full bars or 1 less than full.
If anyone figures it out I would love to know how to solve it.
I get this too. Im trying to debloat the rom of some apps that seem a little suspicious. Will do this tonight. Already backed up my current system partition in case I break something. Wish me luck! :good:

Tell us how it goes. I have actually converted the Amazon ROM to the OEM version, however, that doesn't fix the problem.

Me too. And I have debloted OEM rom to what I consider closest to slim or stock. We'll see later how it goes.
i've pretty much ran the Prime version debloated or the OEM debloated, same thing. I think it has to do with the phone radio and Android 6?
When I put it on airplane mode with only WIFI turned on, phone idle isn't as bad.
Maybe its kernel controlled? Have u tried flashing the 6.6 updates radio.img? Does it contain one? I only used prime to power on the phone from then on only OEM version debloated. And as you say its always consuming batt on idle. I'll give airplane mode a try today.
Alright, I have just installed the xposed module "MobileRadioActiveFix" so this will confirm if it is in fact the data that's impacting standby battery. However, not too sure because "Intelligent Battery Saving" does disable data over time and the draining is still happening in that mode.
Anyways, I'm going to be testing this and report back. @l33chpda @Alex_XV6700

I figured it out, I was monitoring the CPU states and the CPU is not using a hot plug. It nevers makes a core go offline even when the screen is off and it will ramp up while the screen is off because there doesn't seem to be a cap when the screen is off.
I think the only way that we are fixing this is if someone makes a kernel with a hot plug in it.
With Prime 6.4 mine lasts a month on Wi-Fi.

Yes, it doesn't make a difference. I do consistently get 4-6 hours for every two days, however, I can get more if the idle battery life is not there. For example, with your chart, my idle time would be about 45%-55% above the screen.
It's just the way it's reported in this ROM. Instead of looking at the battery stats, just look at the actual battery life of the phone, which is fine.
I have stock V12 vanilla ROM, and I find the standby drain can at times be worse than when I'm using the phone, and I'm not sure why. I'll put the phone in airplane mode and put it to sleep right after unplugging it from charging overnight and when I check on it in an hour or so it'll be down from 100% battery to 90%. When I turn off airplane mode and use the phone normally from that point on, battery drain is normal.

Yes, I experience the same thing! However, overnight, it drains about 10%-20% even though looking at the stats it is not even awake! It should only be draining about 1%-3% because it is not really doing anything at night.
Even the screen uses less power than the standby. @waingro808 could be possibly right that it is just reporting the battery stats different, however, on other phones with the phone idle, that percentage is very low and not as high as ours.

The battery stats dont add up either...
As you can see in my screenshots Im still 14% on battery
And it states that between SOT and Idle I have consumed more than the 2500mAh that this phone has on the battery.

Exactly. Ignore the stats and move on people
I got to 48% battery after 11 days, with "Standby intelligent power saving" enabled.
