Breaking News: Nokia Phone Recharges From Thin Air! (1-ups Pre's touchstone)

It's finally happened: True, wireless charging with NO base station.
Article:
The Palm Pre Touchstone will let you charge your Pre just by sitting it on top of the magnetic induction pad. That’s pretty good, but the phone and the charger still need some level of phsyical contact. Its just so.. this year.
Nokia are developing what they hope will be the future of mobile charging - Ambient Power. No, not a charger with a built-in windchime and tibetan prayer wheel (although that would be a big seller at Glastonbury, Nokia, if you are reading this) but rather a technique for using radio waves to remotely induce a charge into a battery.
The Nokia Research Center has some people at work on creating nanoscale materials that can draw charge from any wifi, radio or similar radiation that is in their vicinity. Just leaving a phone laying around where there is significant radio traffic (eg near a wifi base station) could generate enough charge to ‘trickle’ into a phone’s battery.
Nokia researchers reckon they can leech around 3-5 milliwatts at the moment, although they need to get this up to around 50 milliwatts before it is practical. It is a difficult task, and one that may yet prove impossible, but if it pays off it could mean that hunting for a charger may be consigned to the history books.

From a Yahoo! Tech article:
Mind you, harvesting ambient electromagnetic energy is never going to offer enough electricity to power your whole house or office, but it just might be enough to keep a cell phone alive and kicking. Currently Nokia is able to harvest all of 5 milliwatts from the air; the goal is to increase that to 20 milliwatts in the short term and 50 milliwatts down the line. That wouldn't be enough to keep the phone alive during an active call, but would be enough to slowly recharge the cell phone battery while it's in standby mode, theoretically offering infinite power -- provided you're not stuck deep underground where radio waves can't penetrate.

There are already solar chargers mobile
In JAPAN the solar charging systems comes to town in a small stick around the back of the phone that allows to use less batt power... keeping it safe more time... i saw in tv and i never search in google for it... if one is trying to do it please post something about...

wo! so what happens to my head when we reach 50mw of radiation floating around! perhaps we could just put our devices into a microwave and set on low for 30 seconds!
(this is just a humerous post, and isn't intended to offend or infuriate anyone!)

Is this like the wifi charging article from april?

he he! nice one

sweet i cant wait until i have a piece of this technology in my pocket. I also like the idea of having a solar panel on the phone except my phone is in a holster most of the time and i would not like to leave it out in the sun.

WHOAH!!!
this is really amazing if it can be implemented on pocketpc

oid like wi fi charging
that would be cool
its a good thing the whole battery memory issues ws solved though
i think that was when old batteries would forget there chrge oif they kept getting charged repeatefdly

Will your ONE get warm somtimes？

I just get the one for 2days. I feel from time to time it will get warm.
When using internet by 3G it will from 32℃ to 38℃. Sometimes use camera for 2 minutes just it will to 40℃. I use Gsam battery monitor to watch temperature.
During stanby time it is normally 29-32℃. And it is very quick to cool down even it is warm. But I still want to know how others phone is.
Maybe I shall ask for a replacement.

perfectly normal, you will waste our time replacing it, these temps are normal on quad core phones so get used to it
the good use the metallic back cover will help release the heat quickly

Really ？ You are the expert on this. so it works for yours？

and yes those temps are perfectly within the normal operational range, in fact better than the HTC One X
dont replace otherwise you might end up with worth units, its a fact of life
this is what i reported in my review
The HTC One metal back plate did get warm, but never hot, it was clearly getting warm but quickly dissipating the heat

Thanks. As for one x it is in heavy usage it will be hot, but surfer the web can not feel hot.
And for GS4 it is strange I went to shop to play the demo module which is always in charger, but I really can not feel the hot in back.

mate due to the metal plate you feel it more, but for your machine its actually better since heat is being dissipated

I like it when she gets warm, that means shes exited to have me holding her

PSA: Dont ruin your batterys!

Lithium Ion Batterys DO NOT like to be charged at HIGH Temperatures
​After doing a heavy intensive CPU App, or playing a game and the back of the phone is getting really hot, let your phone cool off before charging
I played Plants VS zombies for an hour and the battery temps gradually rose to around 68C which is 154.4F
Let it cool before charging, use a battery temp app such as "Battery" to monitor temps
I learned the hard way on my HTC One X after letting it overheat and then charging it while it was overheating it reduced the capacity of the battery ALOT and got the Red light while flashing when charging witch means the battery has overheated
Also
Your Phone does not have any active cooling system for the CPU, it has Passive cooling witch uses the environment's temperature to bring down the temperature of the internal cpu
Your PC has Active Cooling (Heatsink + Fan)
The nexus 5 has passive cooling (Heatsink only)

same goes with just casual wireless charging. be careful
A battery dwelling above 30°C (86°F) is considered elevated temperature

I can't care less. It has 1 year warranty.

Odd, Is it really monitoring the battery temps? it seems to be linked to the CPU temp and the warm part is located on where the CPU is at and not the battery.

Explain my dead HTC One X battery? Exactly not everything works as it should be.
http://www.ti.com/lit/ml/slyp087/slyp087.pdf
if the temp gets high enough the chip cannot react fast enough
or if the charge falls too low lets say 2 volts it cannot charge again because it isn't a safe charging voltage

I think he was actually saying that the charging circuit wouldn't allow the battery to charge at high temperatures. I cannot verify that but since the charging circuit prevents over draw and over charge by cutting "power" it makes sense

It will cut off after reaching extremes. You don't want it reaching those extremes ever though or it WILL take it's toll on the battery.
Battery's don't like heat. They don't like extreme cold either.

Don't think the battery will ever get to 110F as the phone will shut down/not charge at that temperature until it goes down. Therefore, you probably couldn't spoil the battery if you tried with this fail safe implemented.
With someone's personal testimony about a fried phone, I can offer my testimony that I used a wireless charger on my Nexus 4 + played games until hot + charged whenever I wanted to and the phone, which my GF uses now, isn't any worse for wear.

Especially because the Nexus 5 has a Li-Po (lithium-polymer) and not a lithium-Ion battery

Hi
These batteries don't like heat full stop, they are like perishable foods and degrade quicker the warmer they are, regardless of being charged or not. This is why laptop batteries do not do well when the laptop is used mostly on the mains, nothing to do with constant top up charging, it is because the battery is constantly held in the warmth of the running laptop all day and age much quicker.
Lithium batteries do not work well in extreme cold, but this isn't permanent and they return to normal when back to room temperature, and lithium batteries are held refrigerated for storage, just like a perishable food.
Regardless of being used or not, the battery will lose a considerable amount of its capacity just by ageing over a year or two. Given the various safety controls built in, it is fairly difficult to cause much more damage than time alone will cause, so you might as well just use and abuse the battery anyway, especially as most people will be replacing the phone after a couple of years.
Regards
Phil

i dont think you know what the fail safe temperature is
http://productforums.google.com/forum/#!topic/nexus/cVuWVDW-hyY
there's a thread with someone's n5 getting to 45C(113F) while playing games and without shutting down, and he lives in Canada. imagine what temp it would be at in any reasonably warm climate
110F is not safe if you want to preserve the longevity of your battery. period.

It drained rapidly and the backside was always hot when it wasn't even in use just sitting on my desk caused it to got hot
and i would charge it to 100% and took it off the charger ~10 mins it dropped to 70% just sitting there idle and the back is super hot
my point is the charging circuit only controls for overcharge with is extremely dangerous

Just another example of Google cutting costs to put out this cheapo piece of %$))$!
But actually I did manage to really cook my phone! I set it (plugged in!) in a south-facing window to shoot time-lapse and oh-so-cleverly the sun bright winter sun was streaming through the thermal glass, and on to the silky black phone and...physics happened! About 15 minutes in my insta-greenhouse and I heard a strange whimpering 'ding!' from the phone -- when next I looked it had shut itself down. On reboot Dashclock was reporting "Overheat" "Not charging", and temp of 60+ degrees (can't remember the exact number but it might have been as high as 68!) Panic & a few minutes in the freezer brought it back to normal.
Take from that what you will:
1. It really dislikes being treated like a tomato seedling.
2. Idiot user didn't understand the 'greenhouse effect"
3. The phone does stop charging and goes into shutdown when things get too hot.
Before you judge too harshly, I want to point out the most obvious factor; a truly earth-shatteringly great phone would have come packed with the necessary technology to protect the phone in such cases -- maybe that would be a fan, or maybe it would be better served with a liquid cooling system, but whatever it should have, clearly Google cut corners yet again!

I'm not the smallest guy on the planet, but can you imagine the size of a the pair of cargo shorts/pants that would be needed to carry a liquid cooled smartphone? Massive!! lol
Fwiw, my N5 routinely gets to 107-111f when doing some intensive things with other background intensive things running as well (i.e. banning trolls on my phone both through Tapatalk and Dolphin while listening to a streaming content on mobile wireless and sitting in the sun soaking up some Vitamin D).

It ain't about the pants, it's about Google being too damn cheap to deliver truer-than-true state-of-the-state-of-the-art! Come to think of it, if Google had the balls to fill those pants we'd have the phone we really deserve!
68 Celsius is about 154 Fahrenheit. But as I said, because it was actually being cooked at the time.

Upgrading the internal battery

I'm curious if anyone on here has tried opening their phone up to swap the battery with an upgraded mAh cell? There are 4,220mAh upgrade batteries all over eBay and I'm really about to pull the trigger on one of them. If it fits and works properly, that is a pretty substantial upgrade in screen on time daily and the difference between me having to charge one to two times in the middle of the day versus being able to go the whole day on the initial charge.

Just cause the listing and label on the battery says a capacity doesn't mean that's true. I wouldn't risk putting in a 3rd party battery that costs $20 (for example) into a $600+ phone

Well I mean that's a given with anything you buy on the internet without seeing it first. As for the price of it, a genuine OEM Pixel 4 battery is $25-$30 so I'm not put off by the $10 difference in price. I also am not going to be relying on the battery if I try it, as in if it turns out to be a dud I would just immediately swap back in the OEM battery and take the little $20 hit but I think its Worth trying with the current risk to benefit comparison and if it ends up being truthful, even if it's not 4220mAh but more than the OEM 3700mAh it would be a win in my book for the price. I have an inline USB meter I can throw between the charger and phone to measure how many milliamp hours the battery actually took.

If you need to upgrade battery to get more screen time each day then you're using your phone too much lol

After my experiences with purchasing piss poor quality aftermarket batteries off Ebay and elsewhere (N6P), I would not recommend it. For the same price you can buy a PD power bank that will fast charge your device anywhere you don't have a charger handy. That and you won't break the back glass. Of course, it would be a totally different story if your battery has somehow degraded tremendously and is now defective. I'd be curious to know what your current battery capacity is using Accubattery. When I bought my P4XL, it was 103%. 6 months later it was 98%. If your battery capacity is still 90-95% I would look at a decent PD power bank and not crack the case open. Even if you pay someone to do the work and get a warranty, your phone will never be the same. Best of luck. :good:

I would think that a battery that's 500mah bigger might not be able to fit in the phone... Chances are that the battery will just be a low quality replacement.

According to accubattery I currently have 12 hours and 25 minutes of screen on time. I dont know about anyone else but that is really good in my book and more than enough. My battery is reading 103% capacity.
I never fast charge my phone unless I forget to charge it overnight and I am leaving the house soon then I throw it on the original charger. And I almost never charge past 80%. I actually use a device called chargie that slow charges my phone overnight. It completely shuts down the charger at 80 allows the phone to discharge to 76 and kicks back on and goes back to 80. My battery only goes up about 10 degrees F while charging. And I have it set to shut off the charger if my battery reaches 110 degrees F. I really plan on keeping this phone for at least 3 years (since I have a family and I have to be a big boy and put food on the table now) No more getting the newest phone for me every year.

Well, considering my phone is used for all traditional purposes (YouTube, social media, email, web browsing) along with the fact that I run my business from my phone, you wouldn't be wrong, but it is essential and serves it's purpose. Any extra sot I can get is a huge plus for me.

Yeah I feel what you're saying, the one reason I haven't already dove right in and tried is the splitting the case open. I have don't it once before on a P4, my last one had some issues and I was able to open it up before sending it back to Google to be RMA'd.
I do in fact have a 10,000mAh PD power bank, I bought it within the first week of upgrading from my P2 to my P4. It works fine and is a great solution but obviously being able to fix the root problem would be better if possible. The power bank is along the lines of a bandaid for the problem but seems to be my only logical choice for now.

I just opened up mine the other day to replace the rear glass ( had a crack in the corner). Was pretty easy with the guitar pick looking spudger. I did not need any heat to open it. Figured while I was in there might as well replace the battery with a fresh one. Both were purchased from ifixit. The swap out went fairly quick, I just took my time to scrape all the sealant from the edges of the phone for the back glass to have a good seal. Haven't dunked it yet to test if its still waterproof.

No I actually never ended up pulling the trigger on it. To be honest, I'm still really interested in the idea. The only slight bit of anxiety it gives me is with breaking the factory adhesive on the rear panel. Still, I will try it soon. I hate having to dedicate a pocket to my power bank anytime I'm out for more than a couple of hours.

The 3 pull strips for the battery didn't fully come off so there was still some that I could reuse to secure the battery. The rear glass that comes from ifixit has everything (nfc,qi, camera lens gasket etc) already attached to it including the adhesive. They also sell just the adhesive strip by itself if you're just opening it up.

Question How do you charge your phone when you first buy it? S21 Ultra 5G?

How are we supposed to charge the phone? Do I let it drain all the way to zero the first few times, to "calibrate it" and then try to keep it between 80 and 30 percent?
I've heard getting to go all the way to zero is really bad? It also causes the battery to heat up a lot when it's being recharged?
I've gone through one charge cycle so far. And charged it at 11%. I wanted to let it go to 1%, but chose not to.
Someone help me with this. What is the best way to treat the battery when you first get it?

I just charge it when it goes low and I have time to plug it in. I don't have a specific preferences, whether @ 30, 20 or 15% regardless. I don't think there are any special requirements for that, though I see ppl create their own beliefs and the'd swear to it as "the most optimal charging routine".

Thanks man!

Any other opinions would be greatly appreciated.

At this point in battery tech i believe it doesn't matter. But a lot of ppl and articles suggest to keep phone in 20-80% range.

I did charge it up to 100% when new, then let it get down to about 25%, but generally I try to keep my phones as close to 50 as possible, with shorter frequent charges. I have wireless chargers on my desk at work and home, so it's simple to just set them there occasionally as needed. I have fast wireless charging turned off to keep heat down, and an app on the phone with an alarm that goes off when the charge hits 75%, but I'll often take it off closer to 60 if it's convenient. I'll put it back on around 40%. I'll charge it up further if I'm going to be out for a long day, and will plug it in if I need a faster charge. https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

i use accubattery and use its alarm function to alarm me by default 80% charged

or better to not have a smart phone at all if people get so picky!!
Guys, just do as the phone tells you, when it reaches 15% .. put it on charger until 100%. It gonna last at least 1-1,5 year before you notice the degradation of the battery.

Using the same method as @nightoooo above.
I'm only on my 2nd phone, first was $99.00 phone that lasted 3 years and now over 2 years into my Samsung A20 with no noticeable change in battery life.

I use the AccuBattery app with IFTTT and a smart plug for the charger. I set AccuBattery to create a notification when battery charge reaches 76%. This creates a notification saying to disconnect the charger once a 76% charge is reached. The Android device service in the IFTTT app sees this notification and then IFTTT sends an order to the smart plug’s app telling it to turn off the smart plug. I have been using this configyration for several years and it works like a charm. My previous phone, a Pixel 2 XL, has never been charged to 100% and after 2 1/2 years of use the battery is still working fine.

My 10+ lasted 1.5 years of heavy usage.
It then failed. Don't delude yourself as to the longevity of Li's. You may do better or worse.
Batteries are cheap and relatively easy to replace. A Li failure can total the phone.
Regardless how long it last once it's capacity is less than 80% of it new capacity it's time to replace it.
Degraded Li's are more likely to fail.
Signs of failure; sharp drop in capacity in a short amount of time, erratic fast charging, case bulging ie battery swelling which can damage the display or worse.
There's no reason to discharge below 20% except to calibrate. Charging beyond 90% takes too long and is stressful on the battery.
Li's prefer frequent midrange power cycling. This isn't a NicCad or a lead acid so forget those rules. 40-70% is near ideal.
Charging start temp should be 82°F or above.
NEVER attempt to charge one that is 40°F or less.
Avoid letting charge temperature go much over 100°F.
Regardless of the charger or time, it will stop charging at 100%... if you insist.
I use midrange power cyvling with a fast charger because it's quick and convenient, more bang for the buck. If I replace this battery next month I really don't care as at this point it's just routine maintenance to me.

Here we go again. No, they're not easy to replace for the average Joe.

Don't make me laugh too hard... I was once like you. Have someone do it for you. I got mine done for $50 and learned.
There's not many phones that are harder than the 10+ to replace the battery.
And it's a cake walk
Replacing the LCD screens on my 5D and MK3 were harder only because you need to line up the one time use wrap around rubber skin perfectly the first time when reassembling.
Still intimidated?

It's difficult to buy genuine batteries in many countries. Most people would rather have an original battery from the manufacturer last longer than have it degrade and replace it with something from a questionable source. Again, the discussion here is how to minimise battery degradation and prolong it's life rather than learn how to replace a battery.
Analogy: If someone asks a question like "How should I drive my car so that the engine doesn't wear out fast and lasts longer?" To suggest that you should not cultivate good driving habits, and abuse the engine, then replace it in a year isn't going to help. This kind of approach may work for someone who like to drift and drag-race or race but not for the average person who likes to take good care of his/her stuff.
Everyone knows that when something fails and stops working, it needs to be replaced. But that isn't what we are discussing here. We'd like to prolong it's life and prevent premature failure.

About a month ago I went on the Samsung Members app and put in a request that they add the ability to terminate charging at a user selectable charge level in their Bixby Routines. I then called their tech support 800 number provided in the Samsung Members app and verbally made the same request. The person I spoke with thought it was a great idea. I have never heard back from Samsung about them implementing such a feature though. It would possibly help if they received many more similar requests. If it was a popular request they would be more likely to add it the their software.

The worst thing you can do is not change out a degraded Li. You risk destroying the whole phone. Excuses are like...
You want to ration your cell usage?
Go for it.
I could add a whole list of things to prolong the battery life but it's not worth it.
The battery is flimsy, cost about $14 and was born to die. Parts are readily available especially a year after the release.
Even an amateur can change one out in less then an hour. Rear covers are about $16 but you won't break it if you don't rush it. But the details matter and you can't force parts or over torque screws, less is better. If you're really nervous practice on some scrape phones which aren't too hard to come by.
It's a lot easier than rotating a set of tires or changing a set of spark plugs.
Right off the top of my head, what you need:
Heat gun, fine tip tweezers (for the micro connectors), the proper micro drivers* (sold in kits just for this), plastic picks, sunction cup (optional), anhydrous isopropyl alcohol with a needle applicator syringe or bottle, OEM adhesive seal for the rear cover and the battery. About $35-50:less the heat gun. Optical aids are optional. Keep room humidity greater than 50%.
Sounds intimidating but it's not. Learn by doing.
*use a magnet to magnetize them if they're not already.

How are we supposed to charge the phone? Do I let it drain all the way to zero the first few times, to "calibrate it" and then try to keep it between 80 and 30 percent?
I've heard getting to go all the way to zero is really bad? It also causes the battery to heat up a lot when it's being recharged?
I've gone through one charge cycle so far. And charged it at 11%. I wanted to let it go to 1%, but chose not to.
Someone help me with tKodi noxhis. What is the best way to treat the battery when you first get it?

I simply charge it when it goes low and i have time to plug it in. I don't have a particular preferences, whether or not @ 30, 20 or 15% regardless. I don't assume there are any unique necessities for that, though I see ppl create their own beliefs and the'd swear to it as "the most optimal charging recurring".

When I first get the phone, I charge it to 100% and that's it.
After that, keep it in the 30-80% range and your future self will thank you.
