Power Saver Mode - Use or Not - Sprint HTC One (M7)

Just wondering who uses this to increase battery life? If so, what do y'all have checked?
I want to increase battery life but wonder if it's noticeable.

I don't use it I get 1 1/2 -2 days with light to moderate use with around 3 hours of screen on time

I use it and get the same as bigdaddy test it out see if you notice a difference each phone is defferent

I use it with just couldn't and display checked. Get great battery but it also helps reduce the overheating problem slightly. I don't notice any difference in performance whatsoever.

To be more accurate, each user is different. The phones are identical.
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).
Again, it'll take a lot to really notice a change in either direction, though.

Correct me if I'm wrong, but the jury's still very much out on race-to-finish style processor governors. Sometimes they do well, sometimes they do badly. Either way, it depends on use case.
I would also hazard that it's very much an oversimplification to say that the phones are "identical." It's hardly unheard of for different production batches to use slightly different components. However, the impact from this is probably negligible compared to variations in user habit (and if it's not, then someone in QC/QA needs to go).

Race-to-finish is pretty much the de-facto standard for every decent mobile device right now. It's even getting pushed onto laptops and their associated CPUs (like Haswell).
And I don't think it's an oversimplification if the differing components are only ones that are using on the order of micro-amps of power. They're not using different spec CPUs or something. That would be insanity.

Thanks Vincent for specifying that for me, I guess it's only roms because I have heard that each phone acts different. But this is new to me the phone uses more battery when it's at low speeds? I usually underclock to save battery while screen on as well as during sleep.

When your phone is asleep, underclocking does nothing, because it's not really even running at all. This mostly applies when the screen is on as well, for any cores not active. 0mhz > any underclock you can manage

Google Tech Support says Patch for Battery Drain Coming Soon

I decided to call Google Tech support for the answer to ask whether the ear piece buzzing is causing battery drain. That's my only concern. I don't care if there's a buzz (the iPhone 4S had it, as did the GN, as do a few other phones).
And the fella I spoke with says the earpiece buzzing is not the father of your baby (/Maury mode) -- I mean, not causing battery drain.
He said it's a manufacturing defect and they'd be happy to send a replacement unit (I said, sure) but he assures that they've looked into it and it's not causing battery drain.
He went on to say Google is planning to send out an update very soon to patch a few bugs, including battery drain issue.
The gentleman sounded legit, but who knows. I hope it is true.
I urge y'all to call Google Tech Support and ask the same. Let's see if there's any consensus.

Pretty certain he's correct,
Hasn't every nexus phone received a fast point release update that fixes a ton of things, improves performance and battery?
Doubt they would change that with the Nexus 4.
It would have been 4.2.1 but due to the December bug, it will have to be something else (4.2.2 probably lol)

wtf is this "battery drain issue?"
For as long as smartphones have existed, people think there are:
- Battery drain issues
- Wifi issues
- Freezing issues
Most of the time the first is caused by a rogue app or bad reception or a combination of both. The second is usually a router issue, and the third is usually a combination of apps interacting or a cell phone that has too much crap installed that just needs a clean wipe.

+1 on the "bad reception" part. I just got a signal booster from T-Mobile for my house (I work from home). Before installing it, my battery was generally around 10% by bedtime. The last two days it's been 40% and 50%. It's a very noticeable difference.

Yeah. Android phones perform notoriously badly with low signal. I lost 30% at work in 1 hour because it kept trying to sync. Compare that with usually going home with 40% left.
Anyway I'm not saying battery can't be improved on this phone. But there really isn't a drain issue present.

Then how would you explain that most nexus 4 drain over 2-5% per hour while idling around doing nothing?
And how about you fix, for example, the msm_hsic_host wakelock that's active up to 50% of the standby time? Come on, I'm sure you can do it with killing background apps!

Yes, custom ROMs are already addressing certain issues. the battery drain and other stuff are definitely present in the stock firmware.
Guys, there are a lot of battery issues threads & guides & faqs and whatever on XDA. Look, for example, for one in my signature. Though it's for my previous device, most of things are still relevant.

There certainly is an issue which I've been suffering. Note in my case there is nothing recorded in the usual battery usage statistics to pin point any problem.
I found overnight and excessive daytime power drain in my case is because the CPU isn't entering deep sleep (using CPU Spy). Typically deep sleep should be in the 90 plus percentage range of all states. In my case it was spending 90% or more in the 384MHz state, so it was never really sleeping, and hadn't entered deep sleep at all, it was an unused state! This causes two problems, one, even though the CPU power drain is small, it adds up over the course of a night or day and eats power, and two, it also means the OS is up and running, so all applications are alive and any app that wants to ping home, download some ads or sync is free to do so which means the cell connection is constantly being kept active trickling packets of data back and forth, causing even more power drain.
Yes an application that has permission to stop the phone from sleeping is often the cause, in my case however battery stats showed no application keeping the phone awake, so I was baffled.
After a lot of troubleshooting I think it might be an issue with applications writing to the emulated SD card, perhaps keeping a file handle open, and this stops the phone entering deep-sleep at a low level in the kernel. As it is happening deeper down outside of Android it doesn't need an application with a keep awake permission to keep the phone awake, and also evades androids battery stats.
In my case I was running Bootlog Uptime, a small app with no permission to keep the phone awake but it does have permission to modify the contents on the SD card and I assume updating a log file on the SD card during the period the phone is awake, probably in order to detect a crash. As soon as this was uninstalled, even without restarting, my phone started deep sleeping.
Now overnight in flight mode it started out with 82% battery, and 9 hours later still had 82% battery! Now out of flight mode, it's been on for a few hours and has just dropped down to 81%.
Note that his application is running happily on a Nexus 7 and HTC One X without causing any issues, hence I think there is some driver in the kernel for the Nexus 4 that is incorrectly refusing to allow the CPU to deep sleep if it sees some activity in the flash memory.
Regards
Phil

Battery life?

What is the expected battery life on this glass? Will it be removable?
I think No and battery life ... I think somethink about 8h, A full time work in poland
Google said a day, but in a review I read 5-8 hours of moderate usage. The battery is not removable.

The battery does drain very fast with heavy use, but there aren't that many things you can do other than navigation and video recording that eat it up.
Just be sure to carry a portable battery charger.
What about an accessory for the glass - something like a sticky little solar panel, that will stick to the handle part of the "screen", and with a tiny cable connect to the USB port for solar charging.
Will it do any good to the battery life?
I mean, will it produce enough electric power over the day time to even be significant?
Can glass be used while charging?

room for improvement
Hi guys,
On the first day when I received my Glass(es) I did extensive trials with them: this means, taking lots of pictures lots, of videos, showing them to everybody around, etc... Battery lasted about 4 hour. This indeed isn't great, however this was heavy, almost continuous use...
And indeed, if you touch the frame it's so hot it's burning.
Now about the theory of operation: Glass is supposed to be a wearable device for seamless micro-interactions - something that stays in the background except to allow rapid glances to perform one activity much faster than with another device (e.g. a phone). So Glass is definitely not designed to play videos (it can, but it's not the device you'd use for that....)... It's for just in time contextual information delivery, being on only the time to do its job then sleeping again.... With this usage pattern the battery lasts much longer.
Now on the technicalities. Glass uses a TI OMAP 4430. That's a pretty old cpu now (released Q1 2011), 45nm process.... really old stuff.... I think it's fair to speculate that the OMAP4430 won't be the CPU used in any commercial release of Glass....
Another thing is that Glass uses Bluetooth 2.... there may be a pattern, with Android now supporting BLE (Bluetooth Smart)... now most the radio chips support wifi, BL *and* BLE... we could also speculate that a commercial release would use BLE.....
Cheers,
Dan
Definitely not - as stated before.

You need to give us the temperature of the phone. Use GSAm Battery Monitor for battery temp.
Depending on your use, case on the phone, and outside temperature, your phone will operate at a different temperature to others. From what I have seen, the phone will operate around 37-40 degrees give or take a degree. If you are gaming or doing something really intensive, it will go higher. Seeing gaming temps in the low to mid 40s would also be normal.
These temps are on stock. Temps can be lower/higher with custom kernels.
The phone definitely runs hot, but HTC would have known this when building it.

Is somebody using JuiceDefender on this device?
Sent from my HTC Desire C
Yeah, been using it for a while, defiantly makes a difference in battery life.
Juice defender is not worth it on low end devices like that. What you get is placebo and the same amount of battery drain as usual. It takes battery just to do the tasks you give it, so its pretty much useless. Stick to greenify.

Battery?

When I got the phone, the battery section of settings would estimate 24-26 hours remaining from a full charge. I'm at 90% and it's estimating 15 hours remaining. Anyone else have this dramatic decrease in battery life? My usage of the phone hasn't changed.
The estimated time remaining is an ESTIMATE based on the current usage. (I'm not sure if it's based on the the current usage from a given timespan, since last unplugged in, or what.) The point is that if you leave your phone idle after fully charging, you'll have a higher estimated time remaining. If you use it heavily right after charging, you'll have a lower estimated time remaining.
In other words, it's kind of saying something like "Based on how you've recently been using your phone, you have XX hours remaining." So, change how your using the phone, and the estimate (actually, more of a guesstimate) will change.

90F is cool for a phone thats on. your body has an average body temperature of 98.6F. my guess is thst you are giving your battery temp. battery safety is st 60C, which is 140F. your phones cpu has a safety shutdown mechanism that automatically shuts down at 105C, which is 225F.
and battery drain, can be pretty bad depending on the game, is very expected.
