Good day..
Xperia z1 has a strange battery usage behavior..
The problem is that ( screen usage percentage%) will not be applied till i put my phone in sleep (idle) mode..
I mean when i am using my phone you can notice that battery % is freez or may be make a very little move around -1 or 2 % ... then when i go sleep idle mode .. i got a massive drain drop in % around 6 : 10 ... or more it depends on the awake and active mode time and the amount of my usage for apps.
( i tested this issue 3 times ... on airplane mode , wifi off and i disabled any apps that may affect the battery in idle .... the same result)
So i am sure the idle battery drain .. can be considered a delayed consum from active mode

I have been using X10 mini pro since the past 3 weeks.
After a few days of discharging cycles, I see a improvement in battery performance. I've already read about the tips section on battery improvement.
I manage to get about 11-12 hours of standby with wi-fi/bluetooth/background data off (No Music, no videos, screen off 90% of time). Screen timeout is set to 30 secs.
I have not installed any other software apart from Helix launcher & Advanced Task Killer.
I observed that when the cellphone is left in Airplane mode for over 10 hours, battery depletes by just 1-2 %.
However, if I leave the cellphone in GSM only mode, the battery loses from 100% to 10% in just about 9 hours with display set to lowest brightness
The signal strength is always between -57dbm to -90 dbm in my area.
I'm not able to understand what is eating up the battery.
Initially I suspected that I'm not on the latest firmware which could be using a lot of battery on cell standby. But I see that the build number is 1.1.A.0.8
Anyone thinks that this could be a GSM service provider issue?
When is the next firmware update coming?

That is true, I have experienced this. It is not the Service Provider issue, it is something related to signal reception. If you are on call for 1 Hr battery, drains by 20-30%, this is too much.
The worst part is short duration calls, everytime you call some one, battery reduces by 1-5%. To make matter even worse, you cannot replace the battery
My battery life was very good in Mini. I used the phone for normal talking (around 30 mins) and 3-4 hrs of GPRS and battery wwas kept around 20-30% at
10PM after fully charged at 7AM. At that time the battery usage status showed something like this.
Display -40-50%
Android System 10%
Cell Standby 2-5%
Phone Idle 2-5%
Others (not remebering)-the remaining
Suddenly two days ago my battery started dischrging very fast and my full charge at 7AM came to zero at 4.30PM with similar use as stated above. But this time the battery usage shows something like this and consumption always remains highest by phone idle & cell standby parameters.
Phone Idle 40%
Cell Standby 30%
Android System 8%
Display 20%
Others - remaining
Now, my battery is draining a lot faster than it ever had two days back.
My battery had consistently been draining at around 1% per hour idle until today. Now I'm seeing it drop 5% in LESS than an hour while idle (idle meaning the screen shuts off and I don't use it).
So my question is, what do Cell Standby and Phone Idle mean? Previously they had both been 2-5% and my idle battery use was excellent. But today they both shot up to the 30-50% range and I'm thinking this may be the cause for the excessive battery drain even while the phone is sleeping.
I have not changed anything during these two days. But again to be sure I "Factory Reset" the phone and reinstalled all the software again but found the problem persisting. Moreover, during my travel to office (which takes about two hours) I find battery drain is minimum and same as my earlier days, i.e., it drains very slowly but once I enter my office hall the rate of drainage increases, But previously in the hall also the drainage rate was very low.
My queston is what may be the cause of this?
The only change which I feel is deterioration is signal level because the calls now frequently gets disrupted which was not the case earlier. Can this be the only cause for such high battery drainage ?
An exactly similar experience can be found in some other blog whose link is below ( for reference only)

Anticipating some advice/solution for improvement from the geeks here.
Thanks
i noticed i had the same issue whenever i installed some apps from the market...i noticed in particular a data counter to screen my phone bills and Quick Profiles.
So i suggest to think abotu the last installed apps and try to remove them one by one until you find the guilty one.
Remember afer uninstall to reboot your phone or you won't notice any difference
Have you recently rooted the phone? When I did mine I found there was a shell process left running that was eating battery (but doesn't show in the battery info screen) - Turning off and on again sorted that out
Thanks for reply. I will try your advices. But today I morning I switched off my charging at 4.45 AM and now at 6.37AM I am seeing my battery at 99% ot bad. Let me see throughout the day.
Even i am experiencing this problem
Phone Idle is 59% and Cell standby 37% for me?
Now i have removed all task managers and Info apps
lets see what happens to the battery life
@acemadmav
Your advise helped me to track my problem. I also use a Data Tracker software which was refreshed at 2 min and was the cause of battery drain. Now I have set it to 30 mins and my phone is back to full battery strength. Discharge started at 7.30AM after full charge. Attended not less than 45 mins of call, an hour of GPRS and I am still at 50% at 10PM.
@tejagamer
My Phone idle & Cell Standby is still high at 30% and 25% respectively. I googled about this and found that "Phone Idle" is the state when phone uses minimum battery required to keep the electronics of the phone alive and "Cell Standby" is battery consumed for communicating with cell towers in standby mode. Finally, when battery consumption is ok the percentage used by Phone Idle & Cell Standby doesn't matter.
Thanks

glad to help...it's been some months i'm "testing" my X10 mini about this kind of things, so i'm getting used to track down problems on my phone
Hello !
i have two access points
one Asus (dd-wrt), i made a ping test to my android and i get ~300ms on sleep mode, my battery drains in 1 day and 18 hours aprox.
Thomson, i made a ping test to my android and i get ~1000ms on sleep mode, my battery drains in 2 days and 8 hours
Does the battery drainage depends on wifi access points you have ? anyone noticed that ?
I think the attachment made my problem pretty clear.... As u can see display is consuming the battery most even it is on for only 15 mins out of 2 hrs span...
Please help me out... Display drains my phone even in deep sleep...
After a night of non-use leaving him with WI-FI ON and found him this morning my phone from 89% battery to 51% ( after 10 hours of inactivity )
But this is possible?!

If location is set to on and with high accuracy, it will consume more power even when idle.
Tap on the graph to expand it and see whether the "awake" is a continuous line. If yes, it means the phone didn't go to sleep. Restart it and see if works correctly. Also, the could be apps which are running in background and keeping the phone awake even though screen is off.
You need to give any phone a few complete power cycles before relying on the percentage indicator.
But if any apps were running and/or you have poor Wi-Fi, that's not a bad percentage drop overnight.
Yes it is possible. It is umidigi.
