Sometimes the battery works great, lasts a couple days. And sometimes, I get strange spikes where the battery drains extremely quickly (see attached images).
I have tried:
1. New device - I swapped my unit yesterday
2. Hard reset - restore all factory settings (and erase everything) off the phone
3. Battery cycle - i.e. let the battery run out entirely, recharge it from scratch
I have also tried diagnosing the issue via the stock battery app, GO Power Master, and BetterBatteryStats, but I don't see anything out of the ordinary when the battery usage spike occurs. Maybe there is some process running wild, but it doesn't seem to do anything...
Has anyone had similar issues? The only non-Google Play store app I have installed is Visual Voicemail - the apk I downloaded from this board.
You have tried everything I would normally suggest, but might have noticed something. Your sharp drop coincides with that red band on your signal bar. The red part signifying no cell tower signal. The sharp drop seems to start there. Is your phone stuck searching for cell towers when it has already re-established a signal? The earlier dip in the battery also has a red bar under it.
Also battery performance is not linear. If you are at 50% after 24 hours, you will not necessarily get another 24 hours. I am alwaysfinding myself at 50% after 18 hours and think, "Cool, I've found the right kernel" but sure enough I'm still plugging it into charge at 24 hours!
I know you say you normally get two days (which is very good) but this is all I can think of.
I use a powerful automation app called Tasker. With it you can set any phone setting to any phone condition. I've just checked, and it is possible to set a profile based on signal strength. With this you could specify a weak or no signal to do any manner of things, from play a notification sound, to turn off 3G and auto-sync. Set an exit task and it will also turn 3G and auto-sync back on when signal strength is healthy again. Might be worth a try.
Edit: If you have root access, Tasker supports the app 'Quick Boot Plus' as a plugin. With this you could set Tasker to reboot your phone if it is out of signal for more than 'x' seconds. I know it might not be very practical, but it would tell you if you we are looking at the real culprit.
Another edit: Scratch that. You could set Tasker thatif it sees no signal for 'x' seconds, turn on airplane mode, wait 'y' seconds, turn off airplane mode. No need to buy a plugin.
Thanks, wnp_79 - appreciate the thoughtful response!
Yes, that's a good point - there is a drop in battery starting with the red line for the signal. I take the subway to/from work in the morning and evening. But I don't see any problems connecting after I get outside (i.e. it doesn't seem to be searching for signal).
Perhaps next time I can try setting airplane mode on/off when I notice the battery draining quickly - and see if that helps the issue. If it does, clearly it's a signal issue.
I like the Tasker idea, I will give that a try! Thank you for the suggestion.
I wasn't by any means expecting another 24 hrs, but that drain of "50%" occured over a span of like 3 hours... with no screen usage (i.e. the phone was just sitting next to me at the desk, supposedly "idle").
Whatever you do, don't cycle your battery deeply unnecessarily.

Thanks tsleng, will keep that in mind.
I guess I am surprised other people haven't seen this issue. Maybe it's something specific to my software...
I've got this issue but it's down to my signal. At home it's fine and battery last's me well but as soon as I get to work my battery starts to dip due to Vodafone having poorer signal. Bad signal is killing my battery too bad we can't change radio's as of yet due to no S-OFF.
what happens when we can s-off? i mean what adv will we encounter regarding with the issues that we are having?

Well S-OFF, we can unlock bootloader without having to use HTCDev meaning we can revert back to stock easily and without it tampering the status. We can lock it back to it's original state.
We can flash kernels without having to use fastboot.
We can flash radios. By flashing other radios we can improve our signals if one radio is bad, an improved signal is friendlier on the battery.
I get a weird spike too but mine causes the phone to die. Also mine was done overnight when I was sleeping. (see attachment) I'm not really sure what I can do. I hope this was a one time problem...but i'm not so sure. I'm still under warnty and this is my second HOX

Hey guys,
I have been trying to solve this on my own for two days now, but I would like to consult the forum now.
So, I was running Pink Sense 1.8 for about 2 weeks with setCPU profiles and was getting satisfactory battery life. I had re-calibrated the battery info maybe 2 weeks before flashing the Pinky ROM (as described here: http://forum.xda-developers.com/showthread.php?t=755903).
All of a sudden, without any app installation or change to either the ROM or software/hardware settings I started getting horrible battery life. The battery would drain completely for less than 6 hours with GPS, 3G, and WiFi off.
*Another strange thing (which I don't know if it was related to my battery issue or not) was that when I would plug the charger it would turn the screen on but switch to the default clock app instead of the HTC sense homescreen. If I pressed home or back it would disappear. This would happen randomly and not always.
So, I figured it's time to jump ROMs and I decided on LeeDroid. I wiped cache, etc. and flashed the ROM. Out of the box the battery life was again pretty crappy (the battery was virtually disappearing in front of my eyes). I found some threads where it was suggested to disable market notifications and that slowed the battery drain a bit but it's still crappy.
I just charged it fully, 3G and WiFi off, and was with the screen off for 99% of the time and it still drained 18% battery in 1hour and 25 mins.
So, my question is - what the hell is going on???
Should I wipe battery info? Should I install a non-WiFi n rom? What more can I do?
I would really appreciate help and advice.
p.s. I am running the latest radio too.
wich radio have you the .23 drains the batery with my desire try with the .30_2
the battery life is better.
did you try reboot your phone maybe your optical joystick dead and drain your battery.
load any new apps recently?

As I said, the problem appeared with absolutely no new apps installed and persists after flashing a new ROM.
How do I know if my optical joystick is dead? It still works if that's what you mean (although I don't like using it).
I will try flashing the 30_2 radio, thanks for that suggestion.

If it works he's not dead
after flashing your radio and if the battery still drain check if the rom you use has his own rules for the cpu freq. if you are in that case don't use cpufreq or something like that because of conflicts.

Thanks, I just flashed the 17_2 radio. It doesn't look like LeeDroid has any requirements for cpu frequencies. I will post an update after an hour.

There seems to be no change with 17_2 radio. 15% drop for 1h45m. I will go through a charge/recharge cycle and if nothing has changed I will flash the 30_2 radio.
Some people had the same effect. It happens when you flash your ROM while the phone is connected to power/charging. The battery stats simply get messed up.
An easy indication for this is if you charge the phone fully while powered on, LED is green, as soon as you unplug the charger the battery drops to some 90%.
The fix is easy too. If the phone is fully "charged" while on, disconnect the charger and switch it off. Then plug the charger in again. The LED should turn orange again and the remaining percentage will be charged. Wait until you have a green LED and your problems are hopefully gone.
Look out for the battery calibrating thread here for more info.
Hope that helps...

Thanks for the suggestions. I always thought it would be better to flash with the ac adapter plugged.
I have tried the method you described above but it hasn't really solved any of the problems.
The battery drain is now at least manageable - i had 50% drop while sleeping for 6 hours (at least it didn't drain it completely). I am going to flash the 30_2 radio and try again.

If you have access to a spare battery, maybe you can try that too?
Normally when I have unexplained problems with the phone, the last drastic step I would take is to wipe everything, data/app/cache. Do a nandroid backup first so that if that doesn't solve your problem you could always get back all your setups.
You could also try Titanium to help save your setup. But I would be careful with what I restore. The last thing I would want is to get the messed up setting back in.
I have noticed also whenever I flash a new rom, the battery seems to get worse. So I would always do a recalibration. The proper step is here:
http://forum.xda-developers.com/showthread.php?t=755903 (and wipe the battery status on the last power up before using).
Lastly, I would use as stock as possible first to see if it is things that I introduce that cause the problem.

I think I can definitely confirm the radio is the problem. There is barely any battery drain in airplane mode (1% drain per hour with WiFi on). I am back to 32.43.00.32U_5.09.00.20 but it seems to drain battery faster than before.
Now that I think back, this battery problem started when i switched to the newer 32.47.00.32U_5.10.05.23 radio. No matter what I do now though even after rolling back to older radios it's still a problem. Damn it.

Ok, I have awesome news! Thanks to user "lenik" on modaco forums I got some extra RIL settings (radio settings) he found for Softbank (my cellphone company here in Japan). Here are the settings:
ro.ril.enable.a52=0
ro.ril.enable.a53=1
ro.ril.fast.dormancy.timeout=3
ro.ril.enable.sbm.feature=1
He said the first two should be found on most ROMs, while the last two are probably carrier specific for SoftBank. Anyways, I just downloaded the latest LeeDroid ROM, modified /system/build.prop file (none of the above settings were in there) to include the above settings and ... got a 5% drop in battery for 10 hours on standby (wifi off, setCPU set to 245Mhz when screen is off). This is unbelievable.
Anyways, here are lenik's blog posts about it:

VERY nice results! Do you think that these RIL settings should work on any network/carrier?
It's very odd because today I noticed my battery performance dropping large, BUT before it was always great. I am also on LeeDrOiD 2.1, and while at home, with WiFi + BT on AND connected to my router + handsfree, I lose only about 3-4% an hour.
Today when I left the house and went shopping, I was in the store for 1.5 hrs and I had lost near 15%! I had even turned off Wifi so it wasn't trying to scan APs. Very very strange...
Anyways, I want to maybe try these RIL settings if it will work on any carrier. Does anyone know if I can edit build.prop while in recovery, or do I have to edit it in the ROM .zip then reflash the entire ROM?
Thanks for the post and hunting down a solution slyn4ice, I'm glad that it has helped you out big time!
*** EDIT *** - After looking more into my JuicePlotter graphs, I notice that the battery life gets killed when I am using APN / 3G / HSPA network. I would have thought Wifi would take more power, but that seems not to be so. I DID have "Network Mode" set to "WCDMA only" (in Mobile Network Settings) because I heard it might save battery not having to switch back and forth from EDGE to 3G, but I guess that didn't help...I've since switched it back, but need a lot of charging before I can test again.
Does anyone else notice that when they're on 3G/H the battery drops MUCH quicker than if you were connected to Wifi instead? This is just my last hurdle towards a PERFECT ROM!
Thanks in advance all!
3G uses waaay more power than WiFi. After all, the data usually travels long distances and needs to be amplified. This effect is pronounced especially if in the limit zones of 2G/3G coverage and you have 3G preferred, the phone boosts the power to maximum to maintain 3G.
Gsm Auto (PRL) prefers 2G if 3G coverage is too low. WCDMA Preferred tries to maintain 3G connection even if it means sacrificing battery life.
If you are constantly in good coverage zones, no problem, but to the people living on the edges of proper 3G coverage it meas a big hit to battery life, especially if the mobile data is used. This partly explains why some get superb battery life and others far worse.

Amazing explanation and reaffirmation of my thoughts Jgruar (JuicePlotter confirms it). I guess from my old WinMo days, I always remember Wifi being the power hog. I actually did change it back to GSM/Auto since that was the only change I made lately, but I thought I'd chime in while my device was charging back up, hoping for a reply just like that!
Thanks a bunch!

From what I understand you need to update RIL settings in the ROM and then flash the modified ROM. I just edited the /system/build.prop file in the Leedriod zip file and saved (didn't resign or anything). Flashed the ROM through ROM Manager recovery (I also tried flashing it through the normal recovery but it failed on the "verifying image" stage - I guess because I didn't resign the archive).
As far as the options themselves - only the last two should be carrier specific. I haven't researched anything about them, so I have absolutely no idea what they actually do. "lenik" just copied them from an official Softbank ROM.
God, i just checked JuicePlotter and i dropped 1% for 1h10m (everything off except the radio + setCPU to ~400Mhz when screen off). This is just crazy ... awesome ))))
Is the setting rom specific, or will it work om opendesire?

but no:
ro.ril.fast.dormancy.timeout=3
ro.ril.enable.sbm.feature=1
Just checked.
Firstly, I know what I'm doing when it comes to flashing. But I'm completely dumbfounded here..
Okay in standby mode, with wifi on i usually get -3 to -7mA.
But suddenly a few days ago, my phone doesn't sound my alarm in the morning because it had turned its self off.
Imagine my surprise when I had to plug it to start it. Turns out it had drained 60% in little over 3 hours.
So I began testing - turns out my phone had started to fluctuate between -90 and -150 mA EVEN IN AIRPLANE MODE.
After trying countless solutions (inc many different ROMs), I had had enough. I full wiped from CWM and installed fresh ARHD 5.1.6, skipped all setup, installed just titanium, and restored just battery calibration and currentwidget. I calibrated and then left it overnight in airplane mode - and STILL it fluctuated just as wildly.
I wouldn't post this if I hadn't tried everything, but I have spent hours reading xda trying to amend this. Changing radios didn't help (am using latest atm), changing ROM didn't help (not GB or froyo or CM7), even restoring my nandroid from when my battery drain was normal didn't help.
Does anyone have ANY ideas as to why this is happening?
The only thing I can conceivably think of is that my battery is giving up.
Is this good enough cause to get a replacement battery/phone from HTC?
Edit: Meant to post this is Q&A tread, sorry
if you changed the ROM and radio, then i'd be near to positive to say that the problem is from the battery!!
Buy another one and give it a long 20-22 hrs charge (although HTC recommends 8hrs - but they talk alot of crap ) before opening your phone.
Or, alternatively, see if anyone (friends/family) can lend you a battery and see if the problem still persists

Official batterys are expensive... does HTC do replacements?
not sure, never tried or asked, gotta phone them up!
have you tried turning USB debugging on? that solved it for some people.
i also had this problem, and the USB debug didnt work, but i found that it was something to do with HTC hub repeatedly trying to connect to the internet and using a shed load of CPU in doing so. aeroplane mode didnt help me either, but after turning off everything with HTC in its name it worked again. (specifically HTC sense in accounts and sync)
hope that helps, worth a try.
oh and my battery is fine now, lasts 2 days or so. can last a week though.
still charge it every night though.
Thanks for replying, but USB Debugging was always on for me, and when I tested with fresh install I didn't put ANY accounts in so the HTC thing shouldn't be an issue. i guess I'll just try the replacement battery thing
sometimes the radio signal kept switching also may cause a drain in your battery.
Setting > Mobile networks > Network Mode > Preferred Network Mode
for me i preferred it to be set as 'WCDMA' rather than 'GSM/WCDMA Auto'. The draw back is that i may lost signal if the signal is weak but this setting prevent the radio from being switching.
OKAY GUYS I FIXED IT
How you may ask?
I HAVE NO IDEA
I was just flashing things over trying to fix it and suddenly it went back to normal. I'm currently using a UV kernel, so maybe that's helping too.

Dont want to go too far OT, but how do you measure the battery current?
I assume you dont physically wire up an ammeter, or do you?
Ian P
Hahahahahaha, that's brilliant. I'm signaturing that
But no, I don't. The phone creates estimates of the present current/voltage loss, much the same way as it makes estimates of the battery % left.
So all you need is an app to log that! Currentwidget is the lightest, but I recommend battery monitor widget
OK its a battery monitoring app, but can you see the current drain whilst actually using other programmes?
Some apps use full screen so even the top status bar is not visible.

I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?
might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)

OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??
Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.
1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.
I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

You are incorrect. But, in any case, I DID calibrate the battery just to cover bases in the case that I was wrong.

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
Sorry to have put you out so much.
You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

when i did a complete quote and re flash i did not setup the exchange account, but the issue continued.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.
Hi guys,
I am hoping someone may notice what's going on with my device... I am at a loss. Attaching all screenshots and dump file from BetterBatteryStats (may need to open in Wordpad for the spacing work).
To summarize, my battery drain is very inconsistent. Some days it lasts a long time, 2-3 hrs of screen time, can stay in standby for over 2 days. And then some days it drains very quickly, like right now - it drops by 3% every time I basically turn on the screen to check e-mail/messages. I think we can all agree that 4 hrs of standby and 15 mins of screen usage should not use 50% of the battery.
I have tried two different units (swapped thinking my battery was faulty), and the issue persists - so I think it has to be something related to my software setup. I am running the AT&T LTE stock phone, 1.85 firmware. I have tried doing the full factory reset (clearing all settings/apps/storage), and cycling the battery.
Some folks have mentioned that my drain seems to begin when I hit an area with low/no signal (I take the subway to work in the morning), and then persists - as if something is trying to sync/connect somewhere, but can't... so it keeps looping and draining the battery.
My autosync is only on for Gmail, Google calendar (not contacts), and Weather (every 2 hrs only). Phone is not overly hot, battery is at 86 degrees right now. My brightness is at 40%.
If someone has any ideas, please share - I am at a loss, I don't know what to do... but battery life has got to be better than this, at least in terms of consistency.
Thanks so much.
Hello, i've take a look to your screenshots and it looks like its clearly not an app that drains your battery.
You talked about weather. How many towns have you got in the main clock screen ?
I read here that if you have too many towns, it can drain the battery ...
Just remove all the towns and setup your home town only in clocks main screen's parameters.
And i recently modified something on my phone, in some hidden menu.
( You should call *#*#INFO#*#* and the menu appears ... ).
It was on "WDCMA preferred" ( 3G+ forced even low !!! ) and i set it to "GSM Auto PRL".
I didn't noticed lots of changes for battery usage, but it looks like i have "weirdly" more often H connection instead of 3G or 2G.
It should be the opposite, and i should be more often on 3G/2G ... ...
Maybe its just your phone trying to connect to a WDCMA network that is very poor and that drains battery.
Setting the "GSM Auto PRL" appear to avoid this kind of "forced" connection to WDCMA network and minimize battery consumption.
Here is more information on that point i found here on XDA : http://forum.xda-developers.com/showthread.php?t=688492
Just try another "preferred mode" and see what happens ...
Good luck
Thanks DanRZ. I only have 1 town for weather (New York), and I am on the LTE network - so not sure if those various modes are applicable?
if you are on lte than you are in the wrong forum... the one x cant connect to lte
Ah man, didn't realize there was a separate one. Thank you!!
Btw something is keeping your device awake , it doesnt go to deep sleep---- Sorry i have made a mistake i saw like 7 hours awake in badass , it was minutes . Also what i have noticed is that you have 18 min without signal ,maybe that is draining battery - constantly switching data connection
I was having similar battery problems. It didn't seem like there was an app draining my battery...but after I did a factory reset and installed none of the same apps (except for betterbattery stats) my phone no longer had the same battery problems as before. I'm going to slowly install the old apps one at a time until I figure out which one was the problem.
My S4 mini SGH-i257M was malfunctioning so i sent it in for repair. The local Rogers store sent it to FutureTel in Markham [Toronto] Ontario Canada. This is what they did, according to the Completion Report that came back with the phone ...
;RF Calibration performed to enhance RX/TX performance and network connectivity. Passed RF compliance test to meet manufacturer specifications. Adjusted battery level to optimize power usage.
It has been two weeks now and not only has it not malfunctioned, but the battery life is significantly improved - from 2 or 3 days of light use [usually just 2] to 5 days of light use.
What did they actually do? Does the recalibration affect hardware or software? Did they perhaps re-clock the CPU down to a slower speed? Any way to check this? What do they mean by adjusted battery level?
The phone is running KitKat 4.4.2, not rooted.
Thank you,
Mick
Here are three replies from other forums to this same question. Anyone here want to include an opinion? It would be most appreciated ...
The first part (RF calibration) means they adjusted the radio to improve reception and transmission(rx/tx), so your call/network/wifi reception will be better; the battery level adjustment implies they altered the voltage to improve battery life. In both cases it's more likely they replaced faulty parts with fully functioning ones. Good to see you finally got your issue solved Mick
It seems like what they did is install the OS from factory state and give u a new battery and maybe re clocked the CPU. Unfortunately they won't give you the proper information on what they did nor will u able to find it. There are some apps which tell u what system and software it uses but that's about it
All that I can tell you is RF stands for Radio Frequency. Apparently your cellular radio was tuned a bit off from whatever frequency(ies) your carrier uses. I wonder how they calibrate this.
Their statement "Adjusted battery level to optimize power usage" makes no sense to me. It's almost an oxymoron! But then, when signal level or reception of signal is poor, firmware detects this and gives the hardware an extra kick of battery juice. So maybe that's what they adjusted?
I'm really just guessing about RF calibration and battery adjustment. Hopefully somebody more knowledgeable will shed better light, especially regarding your questions about processor speed

I also would like to know what they did with 'improving radio frequency'. Got the same problem as you, and would like to check if it's possible to manually fix the radio/frequency-problem, cause the guys from the repairshop didn't fix anything for me..
Otherwise: is there an app that notifies me when network connection is lost ?
I found this one : (updated url) https://play.google.com/store/apps/details?id=com.cnigrini.networkmonitor that works well..i now see immediately when my phone loses network connection.
However, now i still have to manually reset it by turning on/off airplane mode. Is there a way / app that does these steps automatically ?
So notifies when network dorps, and then refreshes it..
That would be one way to solve the problem i think..
Your link is to an earthquake detection app ???
I'll post more info later or tomorrow.
I updated the url. It's this app: https://play.google.com/store/apps/details?id=com.cnigrini.networkmonitor
It notifies when network is lost. However it doesn't refresh the network unfortunately.
Well, it gets worse. The phone messed up today same as before. A bit more than two weeks after the "repair". I was at home in one of the strongest signal areas. Would not receive or make calls or use mobile data. So back to the Rogers store. By the time i got there it had started working again so i could not demonstrate the problem. Also used a lot of battery power today, about 40% with light usage compared to 15% or less per day for the past two weeks.
What the counter guy at the Rogers store said is that there is nothing wrong with the phone, that all cell phones do this, and that i should adjust my expectations.
Here's another ConnectionChecker app. This one attempts to reconnect ...

Hey Mdawdy, thanks for posting that one, when reading the descripting it seems like this one is doing both things: checking when connection is down, and when it is, puts the phone on/off airplane mode so that it reconnects again.
I will be testing this one for this time now..
It's probably true that all cell phones lose connection some times, for example when being in a place where connection is very low, but the problem with this Galaxy s4 mini is that it doesn't reconnect again when in an area where signal should be good...
Probably some software thing i think..
I'm still at 4.2.2 by the way.
Edit: found out that with a non-rooted device with android 4.2 or above, it's not possible for an app to toggle airplane mode on/off. So there are probably no (non-root) apps existing that will do this .
However a forum member made a tool that does this: http://forum.xda-developers.com/xposed/modules/app-jelly-bean-4-x-airplane-mode-helper-t2385625

I installed and tried this one. Appeared to be working altho i did not have a network drop. Then i turned on, used, then turned off Wi-Fi. From then on the App continually reported that the network was lost even when it was good. Restarting the phone did not fix it. So i uninstalled the app.

For me it's also not working properly, and i bought the full version (
It's not notifing me when connection/wifi drops.. but I only see it when opening the app.
Also, like i said, i don't think there's an app that toggle's airplane mode on/off when gsm-connection is lost, because it's not possible with a non-rooted android phone that runs android 4.2 or above..
Very disapointing..
