Hello experts,
I've been using my trusted S II for several years, when only half a year ago I rooted it and installed NeatROM on it (jellybean). Even before the rooting, probably after upgrading to the official jellybean, I was experiencing the following scenario:
I put the phone on airplane mode when I fly, or simply turn off both Wifi and Data (over 3g cellular network), so to reduce the battery consumption when I go to bed and don't want to be woken up by texts at 3am. I also turn off Sync option so that different apps (like gmail or calendar) won't wake up the device and try to connect to the internet every minute (and fail).
Then after a long period I turn on Data or wifi, and then - BOOM - a massive drain of the battery, which is accompanied by sluggishness in responses to me pressing the screen or even pulling down the status bar. It is as if all the apps that need an internet uplink - Facebook, Messenger, Whatsapp - wake up at once and try to get online together.
Does anyone else experiences this kind of effect? Is there a way to fix that?
Thanks in advance.

I really want to improve the battery life of my Hero as at the moment it only lasts about a day.
What would you say are the best 'battery life saving tips'
Thanks!
I don't have 10 saving tips, but turning off wifi and roaming internet will probably save some battery power and only use them when needed. lock screen after a 1 minute is probably another tip that will go along way.
ddind to what tweedie suggested: Turn GPS off when not using.
All those tips might make battery last 5 minutes longer or thereabout!
Personally I have found that the following settings suit me:
Internet- always on (for calendar and email updates)
Phone set to 2G (GSM)- I switch to 3G manually when actively using internet
Bluetooth off unless I'm actively using it
Wi-Fi off unless I'm actively using it
GPS off unless I'm actively using it
Just to let you know - turning GPS off or on is reliant on the application you use.
ie, if you turn GPS on and dont use a program which requires GPS, then GPS wont be activated.
But for my two cents which i've read around:
- Turn off automatic weather updates
- Turn most schedule feeds to be at least 1 hour (twitter, email, facebook etc). The more the longer your battery will last
- Turn off 3G if not actively using internet (as mentioned above)
- Install "Spare Parts" to check which program is eating your battery the most and consider if its worth it or not
- Turn off contact sync after your initial setup on your phone. No need to keep syncing contacts when it doesn't change too often
Advanced Task Killer - Download and properly close apps down after using them. Shortcut on home for quick access
APNDroid - Disable data services (3G/GPRS/EDGE). Home screen widget for quick access
Battery Widget - Handy home screen widget showing battery life and also gives options for enabling/disabling WIFI, GPS and Bluetooth. Also display settings.
Disable auto synchronization on things like people (facebook integration), mail etc.
Screen timeout - 1 minute is normally adequate, but I suppose there's no harm in turning it down to as low as 15 seconds, just depends on how you use it.
Turning off animations? - Don't know about this but surely it won't use as much memory so can't be a bad thing. (Spare parts)
Basically everything is off unless I need it, then I switch it on.

Wifi. With wifi on all day and barely any usage of 2G, I'm down to the red zone. Without wifi and 2G all day with text, emails, web browsing, etc, I'm only down to about 80%.
I'm kind of puzzled here. When my WiFi is turned on, I have a constant data transfer of about 20 Kbps (10 send, 10 receive), whilst if I switch on 3G, I have no data transfer (unless of course I'm browsing or whatever). Also, the WiFi drains about 10% battery / hour, which seems awfully lot to me. I have already tried to switch off all syncing, WiFi policy is set to never go to sleep. Any ideas?
Try "turn off when screen off". My wifi drains 1-3% depending on reception and amount of sync. Sometimes apps seem to hang when syncing and keep the phone awake more then they should thus draining more battery.

The point would be to have wifi always turned on, so that it notifies me when I get a new email.
Mine seems to be on although it is set to be off when the screen is off because I still get new mails or updates.

Hey everyone. I was wondering if there is a way to set the phone to turn wifi on when the phone sleeps every 20 minutes (for a 2 minute period) so the phone can sync with google voice/ other services (we don't have a data plan).
Here is why I ask. I got a android phone for my wife and she is on a prepaid plan with no data. She is around wifi most of the time. We wanted to cut out carrier texting by using google voice as her texting platform. Currently, If I text her google voice number, she will not see the SMS until she turns her phone on because wifi is set to turn off when the screen is off. I can also change the wifi setting to keep wifi running even when the screen is off, but that seems like overkill (and probably negatively affects the battery life)....So I was looking for a way/app so the phone can turn wifi on every 20 min (for 2 min) so if she has recieved any SMS, the google voice app can sync and alert her that a SMS has arrived.
Thanks in advance.
If you don't mind dishing out £3.99 ($6USD) then 'Tasker' on the market is a great app to control your phones functions. For example, you can have it turn on airplane mode between 00:00-07:00 but have it flip off for a few minutes every hour to sync and recieve texts/calls etc. I use it and it also helps save battery life!

You can modify build.prop file. I'm not sure is that for syncing or scanning networks.

try ultimate juice, you can make it so that wifi turns on every 5/15/30 minutes for 1 minute to sync.
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)
my GS9+ is on the verizon network if that matters.
In the last 4-5 weeks my notifications, especially those with sound have become severely delayed. It is especially noticeable with apps such as:
SmartThings (when doors open and close at)
Nine (Exchange email)
HikVision Connect (Doorbell camera motion notifications)
It seems to happen more often when on wifi, but i can't confirm that.
When I get up at work from my desk it is like the phone wakes up and all of the sudden I get 5-10 notifications all at once. This also happens at home. It is like the phone wakes up and catches up with a bunch of notifications that it forgot to report.
SMS notifications don't seem to ever be delayed.
Was there a software update or app update that someone knows that might be causing this problem?
Granted I don't have Verizon at all, but my s9+ isn't having any notification issues.
Did you try disabling battery optimization? I turned mine off so that the phone wouldn't put apps to sleep and etc. Power savings for wifi turned on? If so try making sure that's turned off so your phone stays connected to wifi when the screen is off.
Any of the power savings mode enabled or other power savings apps you may have installed?
Mobile data plan permitting try running the phone on mobile data only (no wifi) to see if the issue happens as well.
Are there other apps effected by the issue your having? If a select number of apps are effected (and others are not) try getting in touch with the app developers and let them know what is going on.

I'm on Verizon. Similar deal. I let a system update get applied "Just security patches, no big deal", and it broke some of my notifications. Not all of them. Just some of them. I thought this was early Sept, but might have been in late Aug.
It's "doze". It used to only happen if your phone sat still for 20 min, but it was supposed to wake up with movement. Now mine kicks on after 3 min and movement doesn't impact it at all. You are supposed to be able to whitelist apps you don't want put to sleep, but it seems to be ignoring that setting for some of my apps. After three min I can send my phone a message, and it won't alert me at all. It's not until I turned on the screen, that they all come rolling through.
