[Q] Whatsapp battery drainage - TITAN - HTC Titan

Hi Guys,
I have recently installed whatsapp on my HTC Titan, - its a great app, has drastically reduced my international call and text cost.
How ever the battery life of my phone is taking a huge hit. i am talking about 7 hours total from full charge - when i engage in continuous chatting on the app.
Is anyone experiencing any similar issues? - will be grateful if any one can help figure out the reason for the drain
Cheers

Yes, this is because Whatsapp is continiously checking for new messages using your cellular connection. This means the modem is ALWAYS engaged, and you're practially always connected.
Some random website gave call time spec: Up to 6 h 50 min (3G)
This seems about right with your battery usage.
Being connected with 3g basically counts as talk time, Since the mic and speaker are the least of your worries battery consumtion wise.
Normal synchronisation like email is set at 30 minute (customizable) intervals.
This saves a lot of battery power.
Basically, this goes for any app that uses a continious internet connection (e.g. browser, ad supported app, online navigation, chat.)
Note that in some research a while ago someone tested battery usage in games, and it turns out that displaying ads uses more power than running the game itself (assuming the game is off-line).
http://research.microsoft.com/en-us/people/mzh/eurosys-2012.pdf
Whatsapp is one of those apps that uses continious internet connection.
Also recieving email's "as they arrive" also drains power. So does facebook/messenger chat and any app that refreshes their data in the background frequently OR that is ad supported.

I'm using whatsapp, receiving messages during all the day and my battery stands with no problem until night, 16-18 hours. I think that the battery problem is more related with the time you are writing messages, with the screen, our huge screen, on.

I have had Whatsapp on since day 1 and never had any issues with battery and Whatsapp.
If you do continous chat for 6-7 hours I think your culprit is your screen brightness and CPU that keeps your phone locking and unlocking! I get occassional messages on Whatsapp throughout the day and I manage to reply them whenever I have some spare time. Same with emails.
You can even try anything that will keep your phone "awake" in foreground i.e. keep communicating via emails or e-books with screen on and data on - you will have battery drain.
But same activity on intermittent basis will not cause this drain.
Also, your network coverage - the farther you are from the network masts, the quicker you will drain your phone. Sadly we can't do much about it unless you live in a super-connected area.

@jpmalum: are you using push notifications?
@kpn: actually, WP7 has a completely different background processing policy compared to Android. Incoming notifications flow through MS's push notification service which greatly reduces network access. Periodic polling by apps is restricted to intervals of 15 minutes minimum, and device wakeups for different apps are coalesced to avoid each of them generating its own 3G tail like on Android.
Also, KPN should really fix their network settings, tail times on the KPN network are ridiculous, the modem stays in FACH for up to a full minute! I am aware that this is probably better for browsing but come on, a _minute_, really?
I have some power traces from a Galaxy Nexus with a background process doing some network stuff once per 5 minutes. On KPN, the app uses 277.59J/hour, versus 182.05J/hour and 205.47J/hour on TMobile and Vodafone respectively. The difference is not due to signal strength, but comes purely from tail time. Hopefully fast dormancy and the new enhanced FACH state will fix this in the future, but they require carrier support to work.
(full disclosure, I'm a PhD student doing research on mobile phones)

Few Questions regarding the SGS2

Hello everyone, I have a few questions / issues regarding this phone and android in general, here it goes:
Voice Talk: what are the differences between the two apps (the one with the green and the one with the blue background colors)? They seem to do the same things to me.
Energy saving: the energy saving implementation doesn't seem too "smart" to me. I'm cool with setting reduced energy configurations like lower brightness and turning off bluetooth etc when the battery treshold kicks in, but I'd expect it to restore my setup once the battery level goes above the treshold again. Atm I have to manually undo all the changes that the battery saving functionality does, basically once a day. Isn't there a "smarter" app that restores my settings before the energy saving mode kicks in?
The battery: I've streamed 30 min of music from the device to my car's bluetooth stereo, and it removed 26% of the battery charge. I'm on fw KE2 cause it seems that KE7 is even worse when it comes to power consumption. Still, isn't it too much?
Volume: I've turned it all the way up both with the side button and inside settings -> sounds (all 4 of them). Still, if someone in my office is talking I miss a sms reception etc. It never happened to me when I had the 5800 express music, so I'm not deaf
App notifications: I left my phone near my bed, there is at least 3 out of 4 bars of 3G signal, facebook is set on 30 min updates, accuweather on 3 hours, info-costs every hour, the phone never turned off nor lost the 3g coverage, yet it missed completely or partially a LOT of updates
App settings: app settings also seem a bit random. I have an app called noLed to show led notifications on the screen when it's locked. I had enabled it, checked the "start noled after phone reboot" and all, and even if the phone never even rebooted, after a day or two I went it and the first checkbox (activate NoLed) was misteriously turned off...
Thanks everyone,
TD

Not that I'm not following your logic, it just seems kinda silly to have 3 apps for doing something that 1 app would be enough to do. For example, it's like having Street View as another external application, even thought it's just clearly a Maps "add-on".

Yes true but a lot of users are incapable of using stuff that requires effort and need big shiny widgets and hand holding .

I'm particularly interested in a response to the energy saving that is stock on the sgs2.
However what i want to know is if the energy saving is active, or whether 'energy saving enabled' simply means it is ready to cut in when battery gets down to set target.
Any response to the above questions would be appreciated.
Ta in advance.

I don't think there's any difference between Voice command and Voice talk. Different interface is all I guess?

Isn't it kinda silly to have two different interfaces for a program I'm not even really supposed to use via its interface, but via voice commands?....

As far as I've understood, when it says 'energy saving enabled' in the notification panel it just means that the feature is turned on, but it doesn't necessarely mean that it's gone into 'energy saving mode' already.
My issue with it remains, I don't want it to disable account sync, bluetooth, turn down the brightness etc, and the day after, once the phone is recharged, I have to re-enable all of them...

Got it figured out.
Voice command is for when you're sitting down or something and can give the phone your total attention, while Voice talk is for when you're driving or something.
In Voice talk you can enable 'driving mode', which reads out and incoming texts and numbers of the phone which is calling you.
Even with that disabled, you can just say 'Hi Galaxy' or 'Hey Galaxy' and it will start listening to your commands.
(useful while you're just driving and don't want to be distracted by having to hold down the home button (ahem iPhone) or tap the Tap to speak button)
Still a bit redundant (why not just have voice talk?) but at least there's a difference
I now see what you mean about sync being disabled after leaving power saving mode.
Had a scout about and can't find a solution to this.
Anyone have a solution because this is very annoying.

I'm a bit puzzled by the battery life. I mean, afterall they advertise the various components of the gs2 as battery saving (for example the actually turned off pixels of the super amoled, or the dual core).
So, by logic, if the more advanced parts of it are energy saving compared to other less advanced models, why isn't it consuming less battery?....
Any more info?
I have a new question, is it normal under KE2 that the wi fi can't catch the signals almost al all?
At university I couldn't even detect the network, while the guy next to me with an iphone4 had full signal strength. On the train I had 1 line and it kept disconnecting, while my mate with the nokia 5800 express had no issue with it.
Even at my house going from my desk where the router is to my bed right in front of it, it already starts to drop significantly.
Another issue that I've noticed is that sometimes even tho there is 3g coverage the apps won't refresh. For example, AccuWeather hasnt refreshed since the day before, or manually firing a refresh of the contacts in my WhatsApp list ends in a "update failed, try again later" message, but after rebooting the phone it magically works right away...

[Q] Battery Life = Androids greatest headache

My Samsung S3 battery goes from fully charged to "low battery" often before I get home from work. I just put up with it because troubleshooting Android is such a pain even with Better Battery Stats.
But by exceeding my data quota this month I see exactly what the problem is. Android 4.3 disabled data last night because I went over my quota.
It is now 6:02PM and my battery is at 82% when it would usually be at 5% by now. I still used my phone almost exactly the same amount as I have a desktop at work. My battery usually goes down to 5% just doing nothing in my pocket and making a few calls and texts and some music listening.
My poor battery life is due to all the data transfer bull Google is doing in the background every day.
Better battery stats can identify the process like Bam_dmux or fast dormancy, but it doesn't tell you which apps are actually calling the wakelock.
If Android did keep proper track of this I am sure many apps would be deleted (including Google Apps) from phone in a instant.
But it is too much trouble to try to figure out which one it is so we just put up with 6 hour standby battery life when the manufacturer claims 72 hours.
What a mess ..... I am going to have to research "restrict background data" now to waste more of my time.
Looking at Data Usage in setting doesn't help much because it only tells how much not how often
HaHaHaHa: Google Search on = android "restrict background data" gives 192,000 hits
Does anyone know a good site or method to do this?
Fixed Battery Issue
Well I managed to solve my battery problems at least until the next round of updates.
Previously ..... Galaxy S3 goes from full battery to empty by about 4:00PM in the workday ... mostly phone is sitting in my pocket. No surfing, occasional call.
Then I blocked background data for:
1) Play Store (I am tired of useless updates anyway)
2) Medscape
3) MPR
4) EMAIL ( confirmed this does not affect Gmail notifications )
Then Removed Accounts:
1) All associated with Samsung
2) WeChat and program
So only Accounts for Dropbox, Google, Scribd and Whatsup are left
Nothing else changed
It's 10:00PM and I still have 60% battery ..... sometimes getting pissed helps as I have been putting up with this for a month.
Unfortunately I don't know which were the offenders.

Day5
Since I made these changes my battery life has been greater than 60% every single night no matter how much I use the phone. Maybe it was WeChat.....
Play Store Issues from the OP
My battery life bliss was cut short by issues with my gmail account and sync probably caused my "restrict background data" on the play store.
Previously restricting background data on Play Store and WeChat improved my battery life from 100%-0 in 8 hours to 100% to 90% in 8 hours
BUT
This seems to cause issues with gmail and Google sync. Neither would work and I had to uninstall and clear data for both to get them working again. It said the sync was "experiencing difficulties".
Uninstalling and reinstalling gmail and play seems to have fixed my battery issues .... even without background data restrictions.

Battery Life

Eh, what kind of battery life is everyone getting.. I Fully charged mine today, made a few test calls but didn't' talk, after about 3 hrs it needed recharging.. Bluetooth is off, Wifi is on, and 3g data is on...
On 1900 USA StraightTalk
There are tons of factors that will affect battery life. Thing like;
Signal quality (as a former repair tech, I've seen poor single kill a battery in a matter of hours on multiple phones +200hr standby phones)
Apps running in the background (Skype + Facebook kills my wife's 10day standby phone in less than 12hrs),
Apps syncing (Gmail and other apps are set by default to constantly sync)
Shake Screen On apps force phones to never sleep and on the TS it runs at 1GHz with both cores at all times with any screen on apps I've tried.
On my bench tests I get about 20hrs of standby with cellular on with G+, GMail, Hangouts, Drive, Calender, Keep, Now, Picasa, Google Voice left alone to sync as they please. This also includes a baby activity tracker that syncs over 4000 entries every hour.
EDIT
Reread and noticed you had WiFi AND cellular on. If wifi is on but not connected to a network it constantly scans for networks which kills a battery. The same goes for cellular.
I turned off WiFi seems to be lasting
Sent from my Nexus 5 using XDA Premium HD app
The EnSec Patch helps reduce the wifi battery drain issue by scanning every 300 seconds vs every 15. The patch or properly rooting your device is strongly suggested anyways.

[Screenshots]: Battery drain overnight. Need help identifying wakelocks.

It's a stock T-Mobile LG G5. I get around 2-2.5h SOT. Overnight it drops the battery by 8-11%. There are 34 screenshots in the ZIP file below, showing GSAM Battery monitor and BetterBatteryStats data. I've never used BetteryBatteryStats before so if someone could help me identify the culprit I'd greatly appreciate that.
The signal strength is excellent and the always-on display is disabled. The bluetooth and GPS are always enabled. I should mention that last week I put the phone in Airplane mode and the drain stopped, but obviously it's not a solution.
1.) why do you know, that the gsm signal is excellent? Because you can see 5 stripes in the notification bar? That is not real! I can see 5 stripes too, but this at 15 ASU.
But 100% signal is = 30 ASU! So this result can differ even you believe you can see 100 signal quality.
2.) my system is running on 20p. No BT and no Wlan (no NFC) with 8% for 24Std. (150 user apps installed)
3.) wifi and G-Mail polling sucks much battery power too! you should switch it of to compare! or is it real necessary to be on over the night???
4.) what’s about the google fitness app? this app needs power to check the sensors.
5.) Twitter; Google; G-Mail; Fotos are syncing many times! You can see together more then 800 wake ups!
no wonder that this together will suck your battery empty!
i would suggest you to switch off BT and W.Lan over the night! This should spend a lot of battery power too! Same for syncing and background data traffic.
Try to use 3C Battery Monitor app. there you can see the power consumption every 10 min in the night.
read this too! -> https://forum.xda-developers.com/showpost.php?p=74381087&postcount=327
I have 55 ASUs, so the connection is not the problem. Last night it only drained by 1%. I had both Bluetooth and GPS enabled so I don't think they are the problem either. Twitter, Gmail also were enabled and they actually pulled and displayed some notifications, yet the drain was minimal.
What I think sometimes happens is Google app or Play Services goes crazy starts waking up the phone for no reason. Would you agree based on the screenshots? Or could it be some bug in the OS that does this?

iphone battery drain during call

Hi, I'm having an issue with battery drain during phone call. The battery meter consistently shows audio phone calls as "screen on" and drains battery exactly as if the screen was on, even though the screen is off during the call, with a headset being used. Same issue regardless of LTE or wifi-calling. Audio calls on whatsapp and google hangouts (again with screen off throughout) always shows as 50% screen on/50% background.
Is this normal for iphone? Very frustrating as I am used to making long phone calls on android with very little battery drain!
Obviously it's being misreported which can happen but it's suspicious.
Possibly could be malware... iPhones aren't malware proof. Social apps elevate the risk level.
WhatsApp is malware or close enough... I won't let it FB or any social media apps run on my devices. If I can't completely access it by browser alone, I don't go there.
I would take out the trash and go from there.
Use the native phone app instead.
Thank you so much for the information; this website contains a lot of other fascinating stuff as well.
