Ask Engadget: how long should I first-charge a battery?

Ask Engadget how long should I firstcharge a battery

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Bernard, who wants an answer to the age-old question of ensuring you get the most out of your batteries. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“It’s said that you should always leave brand-new electronics plugged in for ‘a few hours’ after being fully charged, but how do you decide that period of time? Is there a calculation depending on the capacity of the battery, or what? Help me, please!”

Nowadays, do you even need to? While memory effect was an issue on NiCad batteries, Lithium Ion units don’t suffer from the same issue. It could also be tied to the belief that most chargers only re-juice batteries up to 95 percent, but we can’t find any authoritative proof on the matter. Let’s turn it over to the electrical engineers and battery experts who read Engadget on a regular basis so we can sort this out, once and for all!

Ask Engadget: best language to develop apps for Android and iOS?

Ask Engadget best language to develop apps for Android and iOS

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Nikunj, who wants to produce his own apps for both sides of the smartphone war. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“I’m a C++ student and I was wondering what’s the best language to develop apps in both Android and iOS? Is C++ enough, and if not, could you all suggest some other languages? Thank you.”

Your humble narrator isn’t a developer, but has scratched out the knowledge that neither platform’s SDK is that germane to C++. iOS, for one, uses Objective-C or Cocoa, while Android at least does provide a C++ developers kit, it’s apparently not as nice to use as the Java equivalent. Beyond that? That’s where we’ll turn this question over to those developers who proudly call themselves members of the Engadget fraternity.

Ask Engadget: can you rent a tablet?

Ask Engadget can you rent a tablet

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Sarah, who would like a tablet, but only for one week a year. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“One week every summer, I go out of town for a convention that I work with. I don’t get a lot of downtime, but when I do, I want to stay connected. A laptop’s too bulky and a smartphone just won’t have the battery life, so is there a way I could rent a tablet with a 3/4G connection for a week at a time? Thanks”

Sarah, you’ve posed your humble narrator a real head-scratcher here. We’ve hunted around online, and found some web-based services that at least promise to do what you need. One that we are familiar with is Xcom Global, who will loan you a tablet if you select one of its MiFi plans, but it’s a service designed more for international travel than a short hop like yours. We found a few places, including RentOurTablets, RentAComputer and RentFusion — but we’re not qualified to say if any of them are any good. As a consequence, it’s time to turn this question over to the Engadget community. If you’ve got any experience of services that you trust and have used before, chime in and spread a little knowledge this weekend.

Ask Engadget: best roaming options for a trip to the UK and ROI?

Ask Engadget best roaming options for a trip to the UK and ROI

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Tom, who wants to know what’s the best option to get connected during a trip over the pond. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“Hi Engadget, I’m a Verizon subscriber and I’ve got an upcoming trip to London and Dublin. As I’m on a CDMA network, my Galaxy Nexus isn’t going to be much use to me, so what options are available to me? I’m only going for 8 days, so we can’t justify a big investment, but I only need calling and GPS (to get around). Thanks!”

You’re right that there’s no CDMA networks in the UK, but you aren’t without options.

  • Of course, the easiest and cheapest thing to do is convince a friend to loan you their unlocked GSM smartphone and buy a SIM card when you arrive in the UK, and then Dublin.
  • Alternatively, you could pick up a pay as you go handset from one of the UK’s budget carriers. Tesco Mobile offer the Motorola Motosmart, its cheapest with GPS, for £50 ($78), but if you can get by with using a map, then the Nokia 100 is available for just £9 ($14).

But, dear commenters, this is where you come in. Got a better suggestion? Throw it into the space below and help Tom stay connected wherever he go.

Ask Engadget: best email phone?

Ask Engadget best email phone

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Arthur, who has asked one of the most dangerous questions it’s possible to ask the internet.If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“I’m out of contract, and my employer is offering me a company phone of my choice. I’m currently using a BlackBerry Bold 9700 and I handle a lot of e-mails on any given day. What phone would you recommend for someone who needs to send and receive plenty of emails during travel and downtime? I’m not tied to an ecosystem and I don’t care about app libraries or anything else — I just need the best email phone on the market. Please help me!”

What a question! Your first concern should be comfortable typing and if it’ll play well with your work server. If you’re wedded to a physical keyboard, then you should probably wait for the BlackBerry Q10. If not, then Windows Phone’s keyboard is pretty good, but the added real estate offered by the Galaxy Note 2 might be more your scene. What do you think, friends? Give the man some options by filling in the comments below.

Ask Engadget: best video baby camera?

Ask Engadget best video baby monitor

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Berry2Droid, who wants to geek-up monitoring his first-born. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“My wife and I are having a baby soon and need a video monitor. We’d like it to be compatible with our Android phones, rather than having a separate screen in the package. We’d also like some sort of visual aid as my wife is deaf so she would need some sort of other signal. If there was any ability to add additional cameras, that’d also be great. Thanks for your help!”

We could certainly point you in the direction of Samsung Techwin’s Video Baby Monitor or Y-Cam’s offering, both of which are infrared-and-internet capable cameras that pump the picture straight to your mobile device. We came a little unstuck on the visual warning element for your wife, however, but that’s why we’ll turn this question over to our faithful group of commenters to see if their knowledge stretches further than our own. Dear friends, help out a lovely couple as they embark upon the majestic (albeit fraught) journey of parenthood and provide some wisdom in the comments below.

Ask Engadget: best connected exercise bike?

Ask Engadget best connected exercise bike

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Mårten, a self-styled Swedish geek with a love of statistics who wants to make a lifestyle change in 2013. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“I’m looking for a recumbent exercise bike that’s able to hook up to a smartphone or tablet. That way, I could also hook it up to my Withings scale and my ANT+ (Bluetooth 4.0) chest strap. I’ve got a need to loose weight, so could your readers tell me if they’ve found anything similar on the market? Thanks!”

Well Mårten, we struck out looking for bikes that just had tablet docks, but you can always just pick up a holder like the Scosche IPD2FR — which would do a similar job. Of course, perhaps the throng of Engadgeteers will know better, and if you do, let us know downstairs.

Ask Engadget: best app building site or service?

Ask Engadget best app building site or service

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Jeroen, who wants to use an app-builder to help realize his smartphone software dreams. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“I was wondering what online app builders you’d recommend? I only want to make a simple app for an event, but I’m wary of services like AppsBar which offer free development. What should I do? Thanks!”

Let’s assume you’re not a hardcore hand-code it yourself type, but do need to dip your toe into the app-building world. A lot of the more reputable app design services charge a fee to build and submit your app, which can be as small as $5 (Magmito) or as much as $120 (Shoutem) a month*. Which should you go for? Well, it’s probably one of the better questions with which to test the knowledge of our Engadgeteers — so, dear friends, if you’ve been down this road before, what would you recommend?

* Plenty of other services are available.

Ask Engadget: best smartphone car mount?

Ask Engadget best smartphone car mount

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Sam, who needs to find a new way of attaching a Galaxy S III to a windshield. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“I’ve ditched my GPS unit for a Galaxy S III in my car, but I can’t find a good windshield mount. Are there any models that don’t use suction cups? For some reason they won’t stick to my window, and yes, before you ask, yes I do keep it clean. Thanks!”

While we wouldn’t recommend doing anything unhealthy, we’ve found a good lick on the suction cup before attaching it sometimes helps. Your mileage, however, may vary. Still, you could always try one of TomTom’s generic smartphone dashboard mounts or perhaps even using a Bean Bag mount? As for a window mount that doesn’t use suction cups? That’s a question we’ll leave for our friendly commenters to join in on.

Ask Engadget: best barebones workstation chassis?

Ask Engadget best barebones workstation chassis

We know you’ve got questions, and if you’re brave enough to ask the world for answers, then here’s the outlet to do so. This week’s Ask Engadget inquiry is from Charles, who’s capping off the year with a fine question about DIY PC chassis. If you’re looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

“I work in motion graphics and it’s upgrade time. I’m a DIY and Windows nut, so I’m looking to build my own tower, but the cases are all so horrible! I don’t need a plastic window, or something that looks like it was designed by aliens — just something that’s sharp, solid, good looking and has a respectable airflow. Is that too much to ask?”

Well, we trawled our brains (as well as a fair chunk of the internet) looking for some classy chassis, and this is what we found:

  • Corsair’s Obsidian 550D may have a plastic window, but otherwise it’s a monolithic piece of imposing black metal that won’t ugly up your office.
  • Coolermaster’s Silencio 650 is hewn from diamond-cut aluminum and drops the plastic window, and given the company’s heritage, should have excellent airflow.
  • Finally, there’s the Lian-Li PC-A71F, which can only be described as terrifyingly sleek.

But what about you all? Let’s cap the year off with some stylish PC cases, peace and goodwill to everyone and a very happy New Year to you, the Engadgeteers.
