Standby Battery Drain - Redmi Note 2 Q&A, Help & Troubleshooting

Hi,
Just wondering how's the standby drain on your devices.
I'm getting around 3% per hour on 3G (Data On), 1% per 8 hours on 4G (Data Off), and 1% per hour on WiFi.
While not bad by any means I'm not satisfied with the results.

3G kills the battery, I get 5-6h sot on wifi, 3-4 on 3G. Really sucks.

2G?
Any experience with 2G, no data, WLAN off, Bluetooth off etc.? The battery of my current phone (Huawei Y300) lasts about 12 days in this mode. What could I expect from the RMN2?

Have not tested, but 12 days is definitely possible.

I am on the stock rom (global stable rom) and I use 3G and Wi-Fi on this phone. Daily usage is: calls - minimum 30 min, gaming (Unkilled) - 30 min, corporate email (push), viber, internet and I can push it to 48 hours. But it's like 2/3s on Wi-Fi and 1/3 3G.
Cheers

Why does data network mode = ON kill my battery?

With data network mode enabled, my battery lasts around 24 hours. With it disabled currently has 63% remaining having been active for 1 day 10 hours.
Is there any kind of happy compromise where I can have all my data services active but not have the horrendous battery drain?
JuiceDefender. This is the ultimate answer to you question. It manages your data connection when your screen is off. With a lot of customization options, like what it has to do at night.
It disconnects data at given intervals of let it be 5/10/15/30/60 minutes. And then turns it on for 5/30/60/etc seconds, waits for everything to finish syncing, and then shuts down the data connection.
Android 2.3.4 + Juice Defender Ultimate, gives me 2 days of batterylife easily. With checking my screen very often.
Of course, it's all based on how you use your phone.

[Q] Wifi vs 3g battery life on Atrix 4g

Hi,
my carrier Three UK only has a 3g network hence so switching off 3g is no possible for me. When at home I always connect to my wifi automatically using a tasker profile and my battery can last over the whole weekend with moderate use. However, when I am out or at work without access to wifi my battery can drain more than 60% in a matter of 10 hours, although I use a Tasker profile which only turns on autosync every hour for just 2 minutes. I could turn of background data completely, but to me that would defeat the point of having apps like gtalk, skype etcv on your phone.
What's your experience of battery life on wifi and 3g?
I have my atrix on Orange UK. I get round about the same battery if i have my phone on 3G and most of the time it says H. I can get much more time on wifi but not the whole weekend because i use it more heavily i guess. Although it also depends what rom your using…stock roms are pretty pathetic on battery life due to blur. I was using joker's cm9 and even though i had 3g on whole day my battery lasted 2 days.

For me, much better battery life on wifi (40-48 hours in weekend on wifi vs 30-36 hours in work days on edge/3G).
When your device is connected to Wi-Fi, then it will consume less battery as it needs less 'juice' to receive data from a Wi-Fi network than a cellular network.
However, if you are on 3G, but have Wi-Fi enabled, then your phone will consume more battery than with Wi-Fi disabled as the phone frequently scans for Wi-Fi networks. The scan time is configurable and stock ROM and CM7 scan every 30 seconds, whereas Neutrino ROM scans every 2 minutes. This means that Neutrino will have slightly better battery with Wi-Fi always enabled as it scans 4x less than normal.
To configure the scan time, you'll have to edit the build.prop.
Regarding your Tasker profile, it's the same thing. Tasker needs to 'detect' when Wi-Fi is on/off and scan for networks in accordance to your personal settings. Therefore it'll still consume battery while it scans and detects.
This brings in the issue of whether it'll be better to use Tasker profiles, or to keep Wi-Fi always enabled and the result will differ for every person depending on the Wi-Fi scan time, or the complications of the Tasker profile.
But putting complications aside, Wi-Fi consumes less battery than 3G, but only when connected.

[Q] i9205 battery consumption

Welcome,
I've just bought i9205. Great device, but I'm a bit worried of battery consumption. When I'm using 3g ( LTE/WCDM/GSM ( auto ) mode ), and have energy saver switched to on, device "eats" 1% battery per every 5 minutes !!! I'm not using LTE ( have no this mode in my mobile tarrif plan ).
I've rooted the toy, froze Samsung Push Serivce, get cassie's xtraliterom, switch energy saver off, and on Wifi at home the device "eats" 1% per 7-8 minutes. Haven't tested it on mobile data mode, yet.
Is that normal ?

No It's not normal. Try turning off 3g data to see if this improves. Something downloading in background is a one cause of battery drain. I can read on the browser and wifi with 6 hours screen time and have 35% battery left at the end of the day.
Browsing for the last twenty minutes on wifi and used 1% mobile data and gps are off. I'm no longer using stock rom but it wasn't much different when I was. On standby overnight with everything off mine loses about 1% an hour.
With everything off, in my case, cell standby constantly consumes 12% over and an 8-hour period.
I posted this in another thread too.
What worked for me:
1. WCDMA only - using this depends on whether 3G coverage is good where you're at
2. WiFi ON always - using this depends on whether you need background syncs and are often near WiFi
I use My Battery Drain Analyser to track my drain rate. Link Here
With those two options, my drain rate during sleep is 0.5%/h.
I realize that solution 1 is not for everyone, but try it anyway, but keep tabs on when you lose cell reception entirely to see if this solution is viable for you.

Cell standby battery usage

I'm experimenting a bit to see if the Omate TS would be a usable replacement for a phone (ie if it would work well during the day to read notifications, use for sports tracking, recieve calls and such).
It started out well - when I took the watch off charging in the morning I activated the phone, WiFi, bluetooth and paired my bt headset, and turned off cell data. I played around with the phone a bit (installed an app, played with that for a few minutes, checked settings and tried some new things there for maybe 10 minutes or so, and so on). I recieved two calls that lasted about 5 minutes each, and checked mails, facebook and such a few times. After lunch the battery showed 78% remaining, which sounded very good.
I decided to take a walk, so I turned off WiFi, enabled cellular data, and turned on GPS. Listened to podcasts through BT headset for the entire walk. One hour walk with RunKeeper, where I checked mail and facebook a few times during the walk.
After returning, the battery was down a lot, to about 25%, ie 50% battery drained in one hour. I checked the battery stats, and it looked like this: (not a link as I can't post links yet due to forum restrictions): imgur.com/WPQJNd4
I'm not surprised about WiFi and BT consumption as I had those enabled and used them quite a lot during the day, but what surprised me is the cell standby adding up to almost 50% of the battery usage, most of which seemed to be drained when I enabled cell data. Is GPS drain included in cell standby as well? Is this to be expected, or what's causing the excessive drain when using cell data connection? Any tips on how to improve this?
My cell coverage during the walk was decent, as I was outdoors and had at least 3-4 bars of reception the entire time.
cell standby is also the highest drain on mine. was on 2g only as well

Mine usually says that too. Although it still easily lasts me the day with the cell on.

I get about 2 days of battery with emails only, light apps use. 3g and wifi on, no bluetooth connected, zero calls.
8 calls, some messages, BT always on with headset, on 2G GSM, light app usage with brightness on min and i ended on 4th day still with 40%battery left.

That's quite impressive!
I tried again today, took watch of charger when leaving for work. 1 call, 10-15 minutes of "play" (installed an app, changed some settings, re-arranged some icons and such). BT with headset, WiFi and phone enabled all day, mobile data connection off. Recieved quite a few notifications during the day that I checked briefly, but other than that quite idle. When leaving the office at the end of the day I had 52% battery remaining.
Not too bad, but out of that the cell standby and phone idle together consumed half of my battery. Reception is ok, ranging from 2 bars to full (goes a bit up and down). I can't complain about the wifi / bt / screen battery drain, seems the phone standby is the only major battery hog for me.
Cell Standby is a battery hog for me too : about 10% an hour. Cell signal is good. Will try now to disable the mobile data to see if it helps.

That's amazing, what is your setup (hw revision, firmware, settings, etc)?
Disabling cell, wifi, bt, gps, lowest brightness on modified stock (the 2014 testing as a base, ensec, xposed) and I can just make it barely back home on 2nd day with light usage (check the time mostly).
In comparison, my Pebble gets to 30-40% on the 4th day and will die out completely by the 6th day.
Even though the cell standby seems to drain a ton of battery, overall it's acceptable. For normal usage (WiFi on, BT on, paired with headset, phone on, a few widgets and apps that are pulling info from the web, receiving a couple of notifications per hour, checking time/notifications a few times, making a few calls and such) I seem to average about 6-8% per hour. Half of that is for the cell standby, so turning the phone off would probably double my battery life.
I know there are a number of "battery saving apps" out there that modify settings and behavior to save power. Mostly stuff like turn wifi off when screen is off, enabling it once every few minutes to check notifications, and similar. Anyone know if these apps can tune the phone power consumption in any way?

I started running Deep Sleep Battery Saver as I had prior experience with it working well on an SII as a set it and forget application, where other similar programs require much more customisation. keep in mind my omate is not a daily driver, it spends half the week on the charger and the other half on my wrist, and I only use a sim card in their sparingly. as such, I don't have proper data, but I've definitely been able to make it through the day with light usage, occasionally forgetting to recharge until the next day
I think there may be something wrong with either the battery or the circuitry which monitors and reports on the status. I can watch an hour long video with negligable 4% battery loss one day, and another day a similar video draining over 20%.
Certainly with all the radios switched off and very light usage my TS was on 92% well into it's 2nd day...
However soon as you use it... it gets murdered.... lol....
From wednesday till now, few calls, bluetooth on, some texts, very light usage.

Still amazing! Which model hardware do you have? what rom? are you running any additional apps or just what's default? I'd love to replicate your setup on my 1/8 1900
--fg
Truesmart, EU 512-4 2100 working sensors firmware with patch, removed some bloatware, all auto sync off (manual), switched to 2G gsm only, brightness to min, bluetooth always on because crappy mic. Additional apps:facebook, my budget book, hangouts, es file, airdroid, quikpic, teamviewer...

Mobile network standby

Hey does anyone know of a fix for the network standby battery drain? From what I've found out it seems to be a problem with Oreo in general, rather than just my custom ROM. I'm down to %4 battery since taking off charge 19 hours ago, with under 4 hours SOT, and network standby is %29. I'd already tried all the things I've seen on Google like switching preferred network and stuff. Still no change.
kind of idem...charge 100, leave it without connection to wifi or data, battery saving...30 per cent of standby on energy usage, 3 per cent of drain in 8 hours. It's good that? (I have stock rom)
