[Q] haptic drain? - Nexus 5 Q&A, Help & Troubleshooting

So I just read this article on haptic feedback and according to it, there isn't any significant battery drain. Just wondering if its accurate or not. Here's the link :http://blog.immersion.com/2012/07/batterylife/

Not sure that anyone has measured it but obviously spinning a mechanical.motor using electricity will of course have some impact on battery

It's just the motor will be so tiny it's insignificant drain.
If you think about it a standard 4 inch bathroom fan uses about 1-2amp which is nothing in terms of electricity usage. So imagine how small the motor in your phone is

It's not only because of a small motor. It's more related to the low running time of the motor. I mean, just think of it, how much time does the motor stay on to drain any juice significantly? Very little. Hence it's kinda inconsequential.

It seems that they did go as far as to measure it, using June 2012 technology from the Nexus One and Nexus S.

Looks like around 1% added drain, give or take.

Where is v6 supercharger?

Can someone shoot me a link please I can't seem to find it. It not really the supercharger that I'm looking for its the battery calibrator that I've seen in the same thread if anyone knows I'd appreciate it. Thanks in advance

Battery calibration isn't going to make your battery any better.

It stated that it could give me a fuller charge. I have a 3500Mah battery so I don't care about that. I just need to make sure I'm getting a full charge. You know all the way to 4200mv
Sent from my Nexus S 4G using Tapatalk 2
You're getting the full charge, don't worry about it. It's not a good indication, due to the fact it's a cheap onboard voltmeter, lithium ion batteries keep their voltage much better than lead acid batteries and keeping the charge and voltage even close to that level for extended periods of time damage your battery exponentially compared to other charges.

Reading the script just now, all it does is a long and winding process to delete the batterystats.bin file. Note that this has nothing to do with calibration or supply capabilities, it is quite literally just the little graph and app usage % in the settings -> battery menu (which is deleted automatically once charge gets between 90 and 95%).
There is a few other things which it fiddles around with which looks like a futile effort to confuse the battery/OS into giving a false value of "full charge" at the least.

[Q] Nexus 5 battery life

im new to this website and im sort of a noob in modding, but i heard people on xda are pros and can give me an inside opinion. i wanna buy a new phone and its either the lg g2 or nexus 5 for me. im a moderate user still in high school so you could say my phone is off for a good amount of time. i was set for the LG G2 but then after some good research i heard about all the problems with the touchscreen sensitivity becoming whacky and all multiple reports of terrible lag and stutter, i come from samsung and i despise lag the suffering i had with their devices was enough. now the main selling point for the g2 is the battery life, which i also heard can be inconsistent. my question goes out to nexus 5 users, as i need someone with personal experience. i use my phone when i come back from school around 4pm for 1-2 hours then its off until about 11 where i use it for maybe a max of 2.5 mainly facebook, whatsapp, bbm and sort of a lot of youtube. will the battery do me good? and how long will it last? I really need some help. PS. they're almost the same price where i am so i dont want comparisons of "its good enough for 350" i need honest(with screenshots if available) performance opinions. i could really use some help guys please
You're good to go.
Check the battery results thread for specifics but 3 hours SoT is about the minimum you can expect without touching anything.

15 hrs. off the charger and 3 hrs. screenontime for me, stock/not rooted.
I'm rooted rommed and I usually get throughout the whole day easy with a lot of instagram group me and heavy texting . I'm a college student and I text a lot I get through the day
Sent from my Nexus 5 using Tapatalk
i wont have any mods on my phone cause i really dont want to take a risk of ruining my phone, so you think a nexus 5 would do well (1-1.5 days maybe) battery wise? or should i go with the G2?

Why?
If you are a heavy user then I would recommend getting the G2 instead, the battery life gap is just day and night in terms of difference. As for the stutters even N5 is not immune to that. For the touch screen issues, I have several friends who have the G2 and NONE of them have the issue/
I'm sorry, but does no one own a charger? It will last you the whole day. That's all that is needed. Put it back on the charger when you go to bed, Take it off the charger when you wake up.

how do different you think it is? like you have the n5 how much juice you get out of it and are you satisfied? as for the stutter, i heard a lot of stories about deteriorating performance and the ram being taken up more than 1.3/2 out of the 2 gigs available. i really cant stand lag which is my im tempted by the n5. im not really a heavy user maybe moderate-heavy, but i do go out on a lot of days and i have a trip this summer, so i need something that wouldnt fail me midday

Thank you!!
"I can keep it on for 2 days straight oh wowee!". I don't get why people want it to last forever, simply charge it overnight. Yes, the nexus will probably last a full day depending on how you use it, but even if you can't, whack it on a charger for 30 mins and you're good to go till you can fully charge it before bed. The charging speed is amazing on this thing, so if you're at 5% before the day ends, top it up, and in 10 mins and you'll have 20% ready for the rest of the day.
Battery lasts all day = Good, usable battery.

Depends on the day but for heavy use its not as good as the G2, both devices have their own set of stuttering events. I dont even know why the N5 has a lot of home screen redraw when there is over 600mb of free RAM.
It can't compete with the G2's huge battery but compared to phones with similar sized batteries it is extremely efficient.

It is much more than the 3000mah battery...it also has G ram for the screen which decreases the screen power consumption by almost 30% according to lg even after features such as knock on and also the kernel of G2 must have been optimized to maximise its battery life
That is why it is leads ahead off phones which have same mah battery.
I just moved from a G2 to N5.
When I got my G2 it would last almost 2 days, after a few months it would barely last over 1. I Tried other ROMs modded stock ROMs and just couldn't get the battery back up to where it was. The other day it fell down a flight of stairs and I had to replace it anyway so I got the N5, which so far I like the battery on. I don't expect it to be as good as the G2 originally was, but so far its doing great for me.

Think I heard N5 has the same "G Ram" they just don't advertise it. It also has the same 20% more efficient LTE operation as the G2 and is more efficient than other 2300 and even 2600 mAh phones.

[Q] What is the difference between classic Li-Ion battery and Li-Po batteries?

I've seen a lot of threads on other forums on this topic and actually didn't find the right answer to the question. It seems more of an philosophical question because some people say something and others something completely opposite. So if anybody who knows a bit more on the topic would like to describe and discuss this for a bit, I'd be really happy! =)
So: What is the difference in different aspects of normal Li-Ion batteries compared to Li-Ion Polymer batteries (like ones in our Nexus 5 devices)?

LiPo batteries are used because they can get a higher energy density in a smaller form factor, and the batteries can be "shaped" to any configuration.
The only real disadvantage is that the LiPo batteries don't typically have as good a recharge cycle life as LiIon, but that depends on so many factors that it's hard to pin down.

Thank you very much for your answers! It really helped me. So therefore I might have to change battery sooner on my nexus 5 than if it was normal Li-Ion battery? Is it possible to do it after 1 year before battery warranty goes off?

Eh, LiPo batteries typically hit 70% capacity after about 700 charge cycles. It will still be usable, but if you compare day 1 battery life to day 800 battery life, you'll see a decrease.

Hmm thank you all for your answers. Yes it's logical that battery will loose its capacity over time but it will probably do it for about 2 years. If it went really worse I could probably just take it to my provider and let them replace it. I guess it cannot be that big of a problem after all =)

By the way guys what kind of a battery lifes do you get on your nexus 5? I get around 1 day (24 hours) with up to 4 hours of screen on time. I've been pretty pleased with battery life. Though I've seen even better results under the Nexus 5 battery results topic.

Main problem in nexus 5 battery is its Heating and drainage problem in a short time.
I personally suggest you no problem in its Battery but use your phone as a phone not like a music system or as a gaming gadget always.
Do not use your phone while charging it.:good:

I am not really a hardcore user I have some apps for checking email, social networks and some news... From time to time I listen to some music or play some very light game but It is very rare I like that my phone works as I like that's why I like to be rooted and running what I want on it and optimize it differently in different moments (between performance and battery life).

Well in my case it is always different... Sometimes I get more than 4 hours of screen on time and sometimes barely 2 I guess it really depends on the mood of the battery
Sent from my Nexus 5 using Tapatalk
Not meaning this thread, but I've seen so many heated debates on how our phones "should" be charged...and how the battery works.... But as said....if in 2 years my 6 hour screen time and 28 hours total is reduced to 5 hours screen time and 22 hours total.....that won't bother me very much.
Just enjoy the phones....forget about battery science.
Sent from my N5, N7, Moto X, G Tab 3 or S2.....
noob but related question. if i am not using it, is it ok to keep it connected to the charger so it stays topped up? or better for battery longevity to run it down to say 30% or so and recharge. i am specifically talking about nexus 5. thanks.
also as one poster advised not to have it connected to charger while it is in use.....
how about when tethering (drains 6% per hour) or downloading (drains 16% per hour), keep it connected or not.
thanks again.

[Q] Pros and cons

Hello Nexus 5 users...
I've been recently searching about this phone as I am about to buy it...
I still can't gather all the pros and cons of the phone so I can make a conclusion
whether should or should I not buy it...
I've been reading reviews but my experience says that user comments are better than reviews...
I would really love if you could type some pros and cons of this phone.
Thank you very much
Buy it, it's a great phone
Sent from my Nexus 5 using XDA Free mobile app
Yes just buy it man. IMO there are no cons.
Hi,
I've only had this phone for one month, so I can't talk about long term usage, but here's my pros and cons so far:
Pros
Very powerful and smooth
Stock Android
Great developer support, and it's very easy to install custom ROMs
The screen is simply gorgeous
Cons
No SD Card slot
No removable battery (it's relatively easy to replace, but not "on the go")
Can get relatively hot when playing intensive games (particularly PvZ 2)
Overall I'm really happy with it, and I think you won't regret buying it
it is an ok phone..considering for the price..for the price of the n5 u could get the oneplus or the g3 if u have the money
pros
cheap price
stock android
great development
cons
nonremoveable battery
no sd slot
not water resistant
no ir blaster
speakers are not that good
battery life blows
camera is not that good

I consistently get over 5 hours sot and 20+ hours total. Not sure what you're doing to calibrate battery but it's not needed and probably eating battery. The battery is very dependent on your signal quality, the apps you use and your usage patterns. The battery on the n5 is not bad. If you're getting bad battery life it's a user issue.

the battery calibration is just to erase the stats that way u could have an accurate battery meter..it will not increase battery life but it will improve the runtime of the system if the system thinks 20% is left when there is actually 50% or more left..u probably dont use the phone as much as me but i could tell u right now that it sucked..and im not the only one saying that

Battery Life Extension

To maximize battery life (I mean not how long it will last between charges but to maximize the long term lifetime of the battery - over the course of years...) you should never let the % get too low, but keep it topped off as much as possible, correct?
Sent from my SM-N920V using Tapatalk
Very true...
People keep showing off screen on times by draining their batteries to 5% or below, which in turn is hurting their overall battery health..It's advised to keep charging the phone frequently whenever the opportunity presents to charge and to keep the battery levels in between 30% to 80% most of the time... Especially since it's a non removable battery here on Note 5.
Came across many articles on Web regarding this subject.
