Insane Battery Drainage - Nexus 4 Q&A, Help & Troubleshooting

Hey, I got my nexus 4 a couple days ago and have been messing around with it. I recently went back to stock and flashed franco kernel. I just played about ten minutes of Modern Combat 4 and my battery fell more than 10%!!! I think it was fine when I first got it so I hope I didnt damage my battery somehow. I did run like 3 mins of stresstest but I did not let my battery temp get higher than 40 degrees Celsius. My CPU temp did hit 70 though and throttled. Im really baffled as what to do... When playing MC4 my phone did not feel overly hot and when I checked my battery temps were around 35 degrees.

Gaming on a cellular device does eat up a lot of juice. Especially a game with great graphics like modern combat. I see you have red lines in your battery status. You must have bad signal or no signal from where you are. That drains battery power as well as it tends to draw more power to try to connect to the cell tower/antenna. (Just in case you didn't know)

I actually dont have a sim card in yet, since I just got the phone.

I've found the phone goes longer between charges since I've broken it in a bit - a few months' charge / recharge cycles (plus expecting to need to recharge after a heavy gaming sesh) have helped

Even without the SIM card it still scans and connects to the wireless network (or attempts to when there is no signal), any cell phone with or without an active plan legally must be allowed to complete a 911 call.
Just one app's performance is not sufficient to determine the state of the battery. Run the phone for a couple of days (without the game) and get a better idea of the overall performance. I'm not sure what franco's kernel gets for battery life overall, but I'm sure other user's have posted in the thread, compare your use vs life to theirs.
In the future, don't stress test your phone. And don't double post threads please.

But my main question is, should it fall so steeply during a 10 min gaming session? If it kept falling like that I doubt il even be able to get an hour gaming time...

That's normal for MC4. I can completely drain my phone in about two hours playing that game.

Alright thanks. The first day I got it I was able to get 4 hours screen time since I was just installing stuff and readying it up. I just got worried that from my stresstesting for 3 mins I might of damaged the battery somehow. I wont be stresstesting again lol.

That's pretty damn good. Game's tend to use up quite a bit of battery, even games that aren't that intense, I get about 4% drop in ten minutes of playing Plague Inc. I don't imagine that game is nearly as CPU/GPU heavy as MC4. Of course I tend to have screen brightness higher, so that burns juice too.

Battery heats up...

I just had a couple of longish calls in a short period. Both averaged about 30 minutes or so.
The phone is HOT. It is hot on the screen and battery side. This is not the first time the phone as started to get warm after long use.
This has never happened on my Raphael. I had it happen the other day while I was using the GPS a lot too. This seems like a very bad thing to me as heat will destroy the battery and possibly chips.
Hmmm....supposedly from the HTC site:
Why does the phone heat up when I’m charging the battery or when I’m making long duration calls? more
It is normal for the device to heat up during charging. After charging, it will return to its normal temperature. It is normal for the device to heat up when you are using the same function for a long time, such as making long duration calls or recording a long video clip. Please rest assured that all HTC devices are factory tested before released. Was this helpful? Yes | No
(I say supposedly because only way to get it was using Google Cache...the page didn't pull up from the link.)
But this isn't 'warm' like I would expect from a battery...this feels hot, like when I tell someone not to put laptop on their lap because blocks vents...and then have them put hand on their laptop. That kind of hot.
Install System info widget and check the temperature of your battery, should be at 98F - 106F
I've had mine get too hot a few times. I'm assuming that's what this means, but when the phone is hot, I see the led indicator light alternate flash between green and Orange. I've taken out the battery and let it cool down and then everything was normal again. I'm beginning to agree with other people that I don't like this phone. I never had this problem, or any problem, with my Samsung moment. If this crap continues with this phone, I am giving the Samsung epic some serious thought. People have ranted and raved HTC phones. The Evo being my first one, I'm not very impressed with it once I played with it for awhile. Yeah, the specs looked impressive on paper but in real life, I don't care too much for it. I guess I will wait and see what happens.

Any idea why the phone would get warm when screen is off and you have no background apps running? I get this at work amd im sure its not caused by signal searching Im outside all night
My phone shut down from heat today.
I got into my car, turned on gps and bluetooth, put the phone into the mount, and started navigation. Sure enough, the thing shut down in about a min. The car and the mount were kinda hot too.
I had to take off the silicone case and point 1 air vent at the phone, to get the temperature to a pretty cool 31C (with charging at the same time).
On its own, I haven't seen the battery heat up, especially when the screen is off.
Perhaps that batter is defective, or you have a rogue process that's running the battery down.
How fast does your battery drain when it heats up, and normally?
The normal speed for draining the battery with the screen off is about 1% per 1 hour.
Covers, cases, holsters, in your pocket, being in a hot car (even not in direct sunlight), etc. Pretty much anything that can keep the heat from escaping the phone or add to the phone's temperature.
I hope cyanogen can be a miracle maker with the custom rom he's making, because this phone's quirks are getting on my nerves. Yeah, it's past the 30 day return deadline.

Which other phone can run 1Ghz processors and not overheat under full load and inside a case?
I think common sense tells me I should have expected that.
I get pretty good battery life from my evo. 20 hours of moderate/high usage took me to 30-40% but I work in a pretty well air-conditioned ambulance and drive around with my phone in my lap most of the time or in my pocket on occasion and when I pick it up sometimes the screen and back cover are warm. I look at battery temp and its like 32-36 degree celsius idling like that
Edit: phones naked btw no screen protector or case for now
After a couple hectic days of ebook reading and killing my battery my phone was getting hot like really randomly and when I had the screen on for like 10 mins or more, or when I charged it or pretty much if I even looked at it wrong! On a side note I have it in the body glove case from Sprint. Also my battery life was horrible. I was going down to like 30% in like 7 hour of practically no use.
Now I was running completely stock and unrooted( I hadn't felt the need to root yet) My solution was I rooted, installed DC rom then and I believe this is what fixed it cleared my battery stats from the recovery menu. Bam my phone hasn't even gotten warm since. Also it's been a week since I did this, and I'm getting crazy battery life now( like I'm down to 70-80% in 7 hours now with light use)

[DISCUSS] Battery Life, MOST Important thing for PLAY phone

Hi All,
Please post about the battery life after using this phone!!
I want to know for how many hours I can play non-stop games
1500mh xperia play´s battery?
I think the battery life is one of the few flaws in this design. I think the battery life wont even be much more then a normal psp. So probably 3-4 hours of non-stop gaming will kill it. That would be a reason for me not to buy this devise.
It's quoted at 5 and a half hours of gaming time.
I had two units on demo 9-5 on Sunday, they were on 9 and 11% be the end, they didn't get any proper recharging, just being topped up a minute or two if there was a gap in people coming to play on them, otherwise they were in use nearly all the time.
So it seems pretty good.
I get around 5 hours of gaming, good enough for me!
my r800x i rooted it and took off all the verizon bloatware and random crap that was running im at 210 free of 300 whatever on the rom side and ive only used 100 mb of the internal memory
only thing i have is snes and n64 emulators and FPse the other day i did about 3 hrs of gaming it was at 100 percent when i started and after 3 hours of gaming i had 75 percent i was playing ff7 and goldeneye
i had wifi off bt off sync off and medium screen brightness only thing i turn on is the sync but i dont need it all the time
i ordered some batterys off of ebay lol i have a bad habit of getting drunk and getting on ebay lol
they should be here today see what happens it suppose to be 2 oem spec suppose to be oem spec but i shouldve known better and the wall plug you just sit the battery in there
1h play, ~20% battery cost with the lights on the powerful setting.
So I confirm, it's around 5 hours of uninterrupted gameplay.
5 hours of gaming might not seem like a lot on paper, but trust me, it's more than enough.
I think people need to remember that this is a phone first, gaming handheld second. For the majority of people, 90% of the day is not going to be spent gaming for continuous hours. I know for me, personally, I play Ocarina of Time on my breaks at work. A typical day for me has me going to work at about 9:10AM, phone's at near 100%. I'll use some WiFi here and there, sparingly throughout the day, and get about 45 mins to an hour of solid gaming in. At 6PM when I'm heading home, phone's anywhere from 70-80%, maybe less if I've been using data slightly more that day. Keep in mind, this is with sending probably 50ish texts throughout the day.
So I get home, I'll usually play for another hour or so more depending on what I'm doing. All in all, when I'm getting ready to go to sleep, my phone's usually at around 65%.
That is absolutely amazing battery life. Any time that I plan on gaming for more than 3 hours straight I make sure I've got an outlet nearby just in case - I carry my charger on my at all times (in a backpack/car/etc) like any reasonable person probably does.
TL;DR - best battery life I've ever seen on a phone that does what the Play does.
5 hours of gaming is what I get, and trust me I've never killed the battery during a normal day. The only time I actually kill it is when sitting at home, and at those times I'm near the charger anyway.
This phone has by far the best battery life of any smartphone I've used.

I agree that the Play's battery life is quite good, but I really have to say that it's not good enough when coupled with 3G usage. I have 3G on all the time, and usually if my day starts at 10am, (with occasional gaming) the Play will die at about 9pm with moderate gaming. That's really quite good, but I usually am not home at 9pm, so it sucks to have the battery go flat just when you are about to start boarding your bus back home.
I wish it could've been a little longer.
Here are a few things about the plays battery life.....
5.5 hours of gaming is really intense and I realistically wouldn't expect many people to actually play games for the whole 5 hours unless they were at home which in that case they will have their charger for the device.
Regarding the phone using 3G, the device will only chew up power if its constantly looking for 3G signal. If the device has a strong constant signal of 3G, it wont eat the battery as much at all.
Regarding rooting the phone to increase its battery life, ive heard and seen that it does actually improve the phones battery life but only slightly. I dont have mine rooted and thats alright by me
Lastly, my experiences with the xperia play's battery have been fantastic. Im getting 2-3 days usage with calls, texts and short gaming sessions.

That, and I'm not sure whether the case I'm using (TPU) supports the extended battery's size.
I'm not even sure whether there are white covers for extended battery covers.. And I live in Asia so shipping from the US is going to painful.

Mobile phones in 2000 were larger and heavier than 300g. Pockets have not changed at all
One didn't buy this phone for its sleekness and fitting his thin jeans, did he?
Vemoxy, you can order batteries and covers from aliexpress.com, they ship from Asia so the shipping fees should be lower. For example: http://www.aliexpress.com/product-f...i-X-pureness-Xperia-Play-Z1i-wholesalers.html

That's because the playstation pocket emulator was made by a team of Sony professionals, and not some dude on the internet.
Sent from my R800
I'd daresay it has a lot more to do with the fact that they have all the data about both the emulated console and the Xperia play. Random dudes in the internet do nit have those kinds of advantages...but still, they do a better job.
Try running Everybody's Golf both from FPSE and from the Market version and you'll find that FPSE renders a flawless emulation which the paid version does not. I know I got pissed off.

Is this battery stat considered good?

I'm no battery stat guy, but could someone tell me if this is considered good battery life.
How long was your display on? You can check by tapping "Display" on that screen.
What level brightness was the screen? Did you use 4g? How long were you on the phone for? You can check by tapping "Voice Calls". Were you doing anything particularly battery intensive?
Looks good to me. Like the user above said see what your screen on time was.

Its not absurdly short, but you could probably be getting a little better battery life. Now let me just clarify that I have ABSOLUTELY no idea what you were using your phone for or how you have it setup so you may be getting spectacular battery life for your specific setup.
Yeah it seems just a little short to me too. I usually average about 3 hours of screen on time with 12 hours of usage throughout the day. About 30% brightness.
A lot of the battery depends on background data, auto-sync, fetching widgets, coverage area, gps usage, gaming, etc etc. So much to account for that the image doesn't tell us.
I'm just trying to have an idea where I'm at compared to most. I just brought juice defender ultimate, so I'm starting to tweak things.
on Bonsai, I can get 3 and half hours screen on before it goes dead playing games.
With 2 hours on, minimal games, regular stuff, on Bonsai I could pull 24 hours probably.
If you are rooted get a voltage and cpu control. for normal web browsing use and talking on phone etc 600mhz at 1150mv is perfectly fine maybe even lower (even tethering). you should also have the cpu throttler tweaked to stay as low as possible.
when you need flash video running or something intensive you should be able to run the phone at 1200 25mv below factory ^^ (does not apply to games)
My downfall was overheating issues so I spent the last day testing things to do with power so I can use it plugged in without getting to hot
*edit
I am going to find the min usage and see whats possible at what speeds/ power without having bad performance
That's about what I average on stock Gingerbread. I've gotten up to 40 hours (weekend, hardly any use at all) on this phone but also have gotten as little as 3 hours (probably a stuck app I couldn't find).
No juice defenders, task killers, etc.

[DISCUSS] Battery Life.

Most threads about battery are quite outdated, so I decided to start a new one.
And so recently my battery is starting to get less muscular.. My Xperia Play is 4 and a half months old, and one hour of consistent 3G usage can drop the battery down from 65% to 24%. I'm not very sure whether that is the norm, but if it is, that's bad battery life, in my opinion.
The Android 'Battery Use' page shows that most of my battery is drained from Cell Standby and System Idle (30%).
My wireless and GPS is always off. Am on 2.3.4 rooted.
Also, Gameboid consumes battery like a beast (even more than 3G), but I guess that's due to the high processing power required for emulation..
Is there any way I can improve the battery life?
Personally I found battery life to be terrible on 2.3.4 so I downgraded to R800i_4.0.A.2.368_World. I'm running 122M-1.5Ghz with scary and BFQ, on top of that I undervolted every frequency as much as I could using incredicontrol (Id give you the values but they vary by device). I always leave wifi, bluetooth, gps and data off when not using them, turned off automatic clock updates (there was a battery draining bug with this a while ago) and I run at 10% brightness with autobrightness off. With this set up I lose maybe 3-5% per night, so for around 6-8hrs in standby while I sleep. Ive got similar results on both cyanogen and stock. That being said I don't have a data plan so I do save a lot by not having data on, but a 40% drop in an hour isn't normal - Ive played an N64 emu which runs the processor full speed for that long and only experienced a 15-20% drop.
imho, the best battery life i've experienced is on 2.3.4.. when i'm on 2.3.3 i always lost 30-40% overnight (wifi, bluetooth, 3g, etc are turned off) stock rom, locked BL..
According to some folks, if you're charging your phone and let it stay plugged in for a while after it hits 100% that screws with the battery life.
On 2.3.4 rooted with all the facebook, timescape and other bloat removed my battery is pretty good. Wifi is on 247 and it reverts to hspda when out. Data syncs hourly, and i have contacts, hotmail and gmail syncing.
The other day i was sitting at 57% after 1 day 3 hours, and that included a half hour go on fpse, might have been more.
Battery life seems good to me. I get 1 day usage then charge over night. I do use my phone quite a lot for this (Tapatalk), Phandroid app, Engadget app, Joystiq app and browser. Wifi and GPS is always on.
At a guess I'm using the phone for about 1 hour a time, about 7 times a day... So like 7 hours web use, phone calls and texts, syncing is set to every hour with FiX on.
When I was on 2.3.3 I'd be lucky to get 10 hours out of the battery but 2.3.4 is awesome.
Edit. Obviously I play games too. Forgot to mention that.

Actually I get similar idle battery drain rates as you, but personally I'm not very concerned with battery drain as long as it's not so much. I'm more troubled with battery life on consistent usage, which I feel the Xperia Play (or at least mine) sucks at.
When I play Gameboid, I get the same fast battery drop too - 40-50% in one hour.

Yep, I read that from a lot of places too. I admit I used to do that (and have since stopped doing that), but sometimes I can't help it if I forgot to charge at night before I sleep (and have to charge overnight to ensure I have battery the next day).

Sigh, I could never get such good battery life..
All the more reason to undervolt, in standby undervolting doesn't have much of an effect on the phone since the processor is either in deep sleep or running at its lowest speed. Also using a governer like scary or smartass helps keep your device running at a lower frequency when possible. Like I said 2.3.4 was terrible for me, 10% drain overnight or more, but apparently YMMV with this. That being said 40-50% drain in an hour is crazy no matter what you're doing on the phone, like I said running N64oid for an hour drops me 15-20% keeping in mind this is at 1.5GHz with sound and the backlight constantly on. If all else fails you can always wipe everything and start fresh, carrying over the same settings while jumping around firmware can lead to some undesirable results. Anyway good luck and keep us posted
The facebook sync option doesn't appear on my anymore, although it used to. To clean it up all i did was :
Purchase Titanium Bakup
Freeze the things I wanted to remove and test rebooting, only freezing a few more each time
Backed up every app
Slowly uninstalled each one with a reboot every couple of apps
Enjoyed my faster phone with better battery life
I use the gmail sync and life.contacts for contact pics
I get amazing battery life on 2.3.4.
In stand-by I lose 1% every 3'rd hours. It's very good in use too. Yesterday I had my day with heaviest use so far and texted like crazy the whole day and a lot of phone calls. Some surfing, gaming and updating of apps between that. Basically the phone was frequently used the whole day with short periods of stand-by in between. At night when I went to bed the battery was at 40%.
Earlier this week I used it minimally for 2 days. The battery dropped 10% for each of those days. But that was very minimal use.
So in short. I have not experiences better battery life on any other Android phone. What takes the most power is emulating. It can suck up like 20% in an hour depending on which emulator I use.
I got my Play at the beginning of the week and with quite intensive use, without WiFi or 3g, I scraped an 8am to 6pmish day on the battery. Admittedly with a fair bit of gaming.
However, that was only waiting for my 2600mAh battery to arrive and now I'm using it, I would recommend it for the bulk. You don't notice it after half an hour or so and I have no issues with gaming on the go whereas I always thought it may die on the stock.
mine drops 4 - 5% /hour..... much faster than b4.... dn no w is goin on w/ ma PLAY.....
I found that since updating to 2.3.4 my battery drains quicker. Usually charge overnight and battery would be around 15% bedtime. (7am - 11pm approximately)
Now I'm finding that by 6pm I'm having to charge it and that's without gaming
brought to you by the XDA app on my badass Android toy
Three times in my first week and a half of ownership I awoke to find it completely dead despite fully charging it or nearly fully charging it before bed. I usually sleep with my phone next to my head so that I can ensure that the alarm will wake me up. That and the lack of a timer function really irk me about this phone. I really hate having to create and save an alarm when I know I only have 45 minutes or 2 hours to sleep (I work a grave shift and have inconsistent sleep schedules during the day). It adds insult to injury when something changes that lets me get another 5, 10, 20 minutes or so and I can't easily add it. On top of that, I have to go back and delete all the alarms I made throughout the day!

Thats crap. Infact you should leave your phone plugged in a good 30/45 mins after it says fully charged if you want a full charge

Isn't it also beneficial to Li-ion's health to keep them at max charge whenever possible?...

Not at true max but at what the battery controller considers max. True maximum will drastically decrease the total cycles just like true minimum only to gain longer cycles in the short-term. When you store a battery it's best to stop at 75-80% because it will lose stored energy slower and not spend nearly as much time near 100%, which is still a trade-off between long cycles and more cycles.
What do you guys think to this?

Its the same size as the standard stock battery so there's no extra bulk... But gives an extra 930mah?
To be honest, I am somewhat tempted... However the question is, will it explode in my pocket and result in me losing half my leg? It's quite a big risk to take! There also might be a voltage difference, however I cannot see anything on that.
Im currently on 1.6Ghz, undervolted. And I just played Order and Chaos for 35 minutes and went from 86% to 63% - I've had bad luck in the past regarding phone batteries, I remember replacing my G1 battery around 7 times, but at these rates my Play would be dead after around 3 hours or less of gaming.
how do you update to 2.3.4 it wont show me =[ please someone answer me :/

You have to expect that with any phone playing an online game. Wifi/screen/GPU/CPU are going at full wack at the same time. What dya expect?

SGN 10.1 battery endurance is phenomenal !

Yesterday we had a day grey in grey and I started my morning as usual with my SGN 10.1
Emailing, Newspaper reading, some drafting for my next lectures, updating apps and then I found some really funny cabaret streams .......
Well, my Note was constantly on and streaming YouTube and some other sources
What shall I tell You: just in time I went to bed it was down to 5%
14 hrs !
No other tab can beat THAT :laugh:
I found a quick way of gaining 5 hours battery per day: I bought my 5 yr old son a Galaxy Tab 2 (early xmas present). Now my note 10.1 lasts me all day, every day It even works with my phone, a Note 2
My note 10.1 has so far been running for 23 hours and 10 minutes and has 26% battery remaining. It's definitely on a par with my previous tablet, an ipad 3 :good:
Last week, took mine off the charger Sunday morning and didn't put it back till Friday night. I didn't use it much, just about 4 hours of screen time. Total time on battery was 134 hours 27 minutes. Still had 55% of the battery left. That standby time if phenomenal.
yeah my last charge was 5 hours 40 mins screen on time and more than 13 days standby. Battery was at 34%. It uses next to no power on standby, absolutely amazing.

I use my Note 10.1 on two day cycles. I am in college and take all my notes with it. I can use the tablet as much as I want and I get two days of battery out of it.
I agree. I'm coming from Asus Transformer Infinity and SGN 10.1's battery is beyond belief. It seems like it's running on nuclear energy. Amazing for such a light tablet.

tbh, it feels as though it runs down a bit quicker than my old transformer prime tf201...
idk though

guys why my screen always say it uses 75/80% when i look at battery usage ?
it makes my battery drain very fast
The amount of time your screen is on is the usage percentage shown eg if you tablet is on for 10 hours and out of that u were using it for 8 hours then the percentage would be 80
Screen is the biggest battery eater which is the case with any device so it effects your battery life the most

I think its what percentage of your battery it has used, not the screen uptime vs total uptime

I got mine yesterday and charged it, hardly did anything with it except download and play a game for less than 10 minutes and have a little doodle with sketchbook pro then left it on standby over night then did a little browsing this morning.
Found the wifi to be slow and sluggish and wouldn't even show all images even though my broadband is 100mb speed.
The battery lasted 13 hours, don't know how long it would last if I'd actually used it a bit more cause it seemed to go down pretty fast even on wifi bout the same life as my s3.
Hardly call that phenomenal.
I'm really disappointed to be honest after reading all the reviews.

Somethings up with your device maybe........ive tested mine a few times, constant use, thats, from 100% untill the 5% warning, mostly browser and youtube......5min break here, 5min break there...........on average 10h MINIMUM of CONSTANT use.........if your dropping 13h without much use, then somethings up with your device and might be worth asking in the q&a thread for help
Are you using full brightness?

Probably just needed a full charge as I only charged it from half way as it came half charged and if that doesn't work I'll do a full discharge and if that doesn't work I'll send it back
Full brightness is too high for me and auto is too low so had it at less than half way.
Only really got it so could use it to take out with me and do some paintings but was worried about it switching off that's why not happy.
Thanks for your reply, really like this tablet and it really is what I thought it would be but if it hasn't got the battery then it's not good.
I'll see how it goes.

Make sure you set WiFi to turn off when the screen is off.
Odd though that the WiFi was slow. It makes me think something is wrong with the WiFi itself that's causing problems.

Personally, I've noticed that the s-pen digitiser, when it is switched on, drains a considerable amount of energy. So do not expect extreme battery life if you use a lot the s-pen. Anyway, do check that the energy saving option under "Options - S Pen" is ticked. This way the digitiser will be off when the stylus is in its receptacle. This will save a good amount of battery when you're not using the pen (provided you insert it in its receptacle). Of course, this setting will have no effect whatsoever while you're using the pen.
In any case, a tablet like this is full of features and components that are potential battery killers, so how long the battery lasts, it's really up to how the owner uses it, and not only how much. For instance, I may be surfing the internet and checking emails all day long without using the pen, and consider it heavy use. How long will the battery last in such case? 15 hours? Ok.
Now, a seemingly opposite case could be this: I may have the tablet constantly standing by, but with the pen off its receptacle. Since I have never used the tablet, I have full right to swear that my usage of the tablet is extremely light. Well, only because I've left the pen out of its receptacle, my battery will run flat in just about 13 hours or so. And what's more confusing, is that if I go checking the battery stats, I will see no trace of the pen being the responsible for such a high drain, so I probably will end up getting the (wrong) idea that the battery life of this tablet is extremely poor.
Another case, among the many, is when the tablet tries to sync using the 3G connection, but gets no answer from the network because of problems of the mobile operator network (server not responding). This causes the 3G radio to remain constantly on and drain the battery very fast. Again, it is very difficult to understand the reason for such a quick discharge. Such an issue happens in certain areas of my city with Vodafone, for instance. When I go to that areas, I have to take care to switch off 3G data connection, or else my battery will be empty in a matter of a few hours.
IMHO the problem is, that android os is very incomplete when it comes to providing information for analysing power consumption, and this has always been the cause of big confusion and frustration.

Ah think that was it thanks had the battery saving in pen unticked, wasn't sure whether to tick it or not.
I only have the wifi as got 3g on my phone so don't need it.
Main purpose bought it for was the pen but now have that ticked when not using it should make a difference
