This is an important update to my previous post "How to fix iPhone battery issue..." which did NOT get my battery back to normal, since it played up again after a little while... Finally, I now found a method that got my iPhone back to normal with a battery life of up to 24 hours and more... I feel like a new human being again and do not constantly have to look for a power supply, but I can now even leave my iPhone 4 on the couch over night and it will not loose much battery life, if I am not using it... Here is how I did it: I set my iPhone up as a NEW phone WITHOUT installing the backup and it was VERY successful and easier as I thought... Maybe took me roughly 2 hours... That's all.

Before you do Set Up Your iPhone as a NEW PHONE, please remember that any data that you cannot store externally will be lost, but there are apps to back up almost everything you need... Here are a few things I did...

1. I used an app to backup all my contacts, which sends you an email with a VCF file... (example app)
   
2. If you want to keep all your text messages, read this article...
   
3. I synched my phone to bring all music across into my iTunes library... (Music can later easily be put onto your newly installed phone without the backup!)... Synching your iPhone is also very useful, if you recently downloaded new apps since you will be able to see all your old apps later in iTunes in order to remember which ones to re-install...
   
4. I copied all my photos and films manually to my computer, using Windows Explorer file copying...
   
5. I made sure that all my notes were synched into the cloud e.g. with gmail activated for them...
   
6. I made screenshots of my smtp and imap email settings so that I could install them easier after I had set up the new iPhone
   

After you Set UP Your iPhone as a NEW PHONE, the real work begins, but it is well worth it...

1. You have to re-install each app manually on your iPhone through the app store... The good news: Apple remembers all the apps you previously bought, so you have not wasted any money!
2. Set up your WIFI
3. Set up your email accounts
4. Check your settings / PINs / locks, etc...
5. When you connect your iPhone to iTunes, DO NOT choose the option in iTunes to install a backup, but rather go through the iTunes flow for a NEW phone!!!

WELCOME TO YOUR NEW LIFE WITH AN IPHONE4 BATTERY THAT LASTS AS IF IT WAS NEW! 

READ FIRST!!! VERY IMPORTANT UPDATE TO THIS POST. READ FIRST!!! 

Three days ago I updated all of the apps on my iPhone 4 and from then on my battery lasted only a few hours after usually lasting all day. The decline in battery power was significant from maybe 12 hours down to 3 hours. I was able to fix it through the help of the Apple support chat. Here is what I had to do:

Follow these steps to erase your device and to install the backup to fix the components that suck up your battery.

1. Install all iOS updates! Check for software updates and install them if available.

2. Transfer the content! Before you erase your device, take few minutes to transfer your content from your device to your computer to ensure that all your critical data is safe.

3. Back up your iPhone! Back up your device before you erase it. Review the steps below, depending on your backup method, to ensure that you have a recent backup in case you decide to restore your device from a backup.
Important: Double check the backup history and settings in iTunes while your iPhone is plugged in and also check the settings you used, e.g. whether you once entered a security password and make sure you know that one!

a) iCloud: Cloud backs up your device automatically once a day when connected to power and Wi-Fi. Review when your device was last backed up by tapping Settings > iCloud > Storage & Backup. You can see the last time the device was backed up on the bottom of the page. If you need to back up, tap Backup now. Ensure that your device is connected to Wi-Fi and connected to a power source before backing up.

b) iTunes: To back up your device using iTunes:

1. Ensure that you have the latest version of iTunes installed.
2. Connect your device to your computer.
3. Select your iPhone, iPad, or iPod touch when it appears in the top right corner of iTunes.
   
   Note: If you have the Sidebar enabled, your device will appear there.
4. Select the Summary tab. In the center portion of the Summary tab, click Back Up Now.
   
5. When this is finished, view the date and time of your latest backup by clicking Preferences > Devices.
   

For more information on backing up your device, see iOS: How to back up. If you wish to copy your backup to another folder, disk, or location for safekeeping, see this article in the section titled "Where iTunes backups are stored on your computer." For more information about what iTunes backs up, see this article.

4. Turn off iMessage! If iMessage is active, turn off iMessage at Settings > Messages > iMessage. No idea why this has to be done, but I did as per Apple instructions

5. Erase your device! Erasing all content and settings will delete all the data from your device, including songs, videos, contacts, photos, calendar information, and any other data. All device settings are restored to their factory condition.

To remove all settings and information from your device, tap Settings > General > Reset > Erase All Content and Settings. For more information about this feature, see iOS: Understanding 'Erase All Content and Settings'.

6. Restore your device using a previous backup

Plug in your iPhone into your computer running your itunes

iCloud

1. Erase all content and settings by tapping Settings > General > Reset > Erase All Content and Settings.
2. When your device turns back on, complete the setup assistant. When prompted to set up your device, choose "Setup from iCloud" and then enter your user name and password.
   
3. iCloud will prompt you to choose a backup. Select the backup you wish to use and then tap Restore to continue.
   

iTunes:
To restore your device using a previous backup, connect your device to iTunes. When your device appears in the source list, right-click your device and click "Restore from backup…". iTunes will ask you to choose the desired backup from the list provided and may also ask you to enter the security password.

Note:
Some Apple services (such as two-step verification for your Apple ID) require Find My iPhone to be turned on. After testing the issue, sign in to your iCloud account and enable Find My iPhone.

Trademob in Europe just released very interesting numbers in an infographic about what it costs to reach a top position in an app store and how many organic downloads app marketing gets plus what the paid download costs are for different European countries and the US. 

Here are the most important findings and our own estimates for Australian app costs and downloads based on the Trademob data plus various multiples we applied:

• (1) The number of downloads in the first 72 hours are crucial, while the downloads of the last 24 hours count even more.
  
• (2) App marketing is therefore essential as it not only increases the paid downloads, but also the organic downloads.
  a) For one paid download gaming advertisers receive one additional free organic download in the first three days
  b) Non-gaming app advertisers receive 0.65 organic downloads for free per paid download

1. What are the elements of the mobile strategy of brandsExclusive?
The first stage is to provide the best mobile interface to our service on the devices they use today. The focus has been on iOS apps first as our audience is heavily skewed to iOS devices over other. We have also provided a html5 mobile website for other devices. This includes providing feature parity on our apps with our website so that customers need to never visit our website if they desire.  

The second stage of our strategy is to go above and beyond to provide interfaces and features that are not possible in a desktop browser environment, taking advantage of the unique benefits mobile devices provide.

It's our belief that mobile devices are the future for e-commerce, we estimated last year that by the end of 2013 most of our visits would be on mobile devices. 

2. Please share a few metrics about your mobile offerings with us e.g. how many mobile users do you have? How many app downloads?
In the last 30 days, 47% of visits have been using mobile devices, approximately 30% being on our dedicated iOS apps for iPhone and iPad. In terms of downloads we are in the top 10 in the lifestyle category on the app store, over 1200 app reviews with average score of 4.5/5.

One interesting aspect is that sales conversions are the highest on our apps, with far and away the most time spent. Customers are highly engaged and also making purchases. The notion that customers still prefer to checkout on desktop browsers and only browse on mobile is not true with us.

3. What is your advice for other online retailers that are considering to build an app or a mobile site?
The answer to app first or mobile website first is not the same for everyone. We have found that building native iOS apps are in fact easier than mobile websites where cross-browser issues are a burden. Not only are they easier if you have iOS resources available but provide a far better user experience.
For us going app first was an easier choice as our audience was heavily skewed to iOS 2 years ago and even now.

So from our point of view, should definitely do both if you are in the eCommerce space. Perhaps mobile website first if starting today, but a dedicated iPhone/iPad app following closely.


4. What are the mobile trends you see in the next few years?
Quite simply, majority audience being on smartphones, feature phones to quickly disappear for most, and using those devices to connect with more people and services than ever before.

Devices to provide more contextual experiences fuelled by being an extension of our senses, those senses to continue to expand, the experiences to get better. Wearable computing to become more mainstream.

5. What are some of the coolest apps you have on your iPhone?

• Letterpress gets plenty of my attention at the moment. Very engaging, but also an intuitive user interface
  
• Triage, makes cleaning your inbox so fast and easy.
  
• Circa News, clean and simple interface for reading news.
  
• Foxtel Go, for live sport.
  
• RunKeeper

The download numbers of popular social media apps and messaging apps on Google's Android app store Google Play are breath-taking. While Instagram reached 1 million downloads in just 24 hours when it arrived on Android last April, now a predominantly Korean messaging service took over the home screen of 500,000 Android users within only 9 days and now already has 50-100m installs. Google shares rough download numbers for each app on its Google Play page and the classical Facebook app is currently listed with 100 million to 500 million downloads, while Facebook's Android launcher Home received 500k downloads within a week, but also a fair bit of criticism through the review function still only with 2.5 stars out of 5. 

Google and its mobile hardware partners seem to have found a winning formular and it is no wonder that Apple is now under pressure. 90 percent of Korean smartphones are already Androids.... pretty much the opposite to the still Apple-dominated Australian mobile landscape.

It is amazing to watch how the internet and mobile space get disrupted by open APIs, open IDs or single-sign on solutions like google+ Sign-On, Sign in with Twitter or Facebook-Login, which already allowed social games or instagram - to just name two examples  - and to grow at unprecedented rates. Most modern websites today have either a Facebook or Twitter sign-in.

In addition to the massively reduced technical entry barriers / switching costs and quicker reach of app users, the Android operating system also allows apps to play dominant roles around the whole usability of a phone and even take over the Home screen as the app launcher of Facebook demonstrates:

Looking into the future, the above means that we will see many more apps that grow at explosive rates e.g. like Instagram, leveraging a clever mix of existing authentication mechanisms, smartphone features,  viral sharing through existing social network APIs plus through running a website with unique content owned by the app developer. Will Facebook and Twitter facilitate the growth of their own competition in the future through opening up so much? How easy will it be in the future to replicate a Facebook or Twitter through simply better usability and more cleverness by tapping into the smartphones of customers and enriching existing Facebook or Twitter experiences plus by introducing value-adding or completely new features that will allow the app developer to then own the user completely? Luckily the big existing social networks incl. Facebook, Twitter, Google, Yahoo+Tumblr!? or the Kakao's of the world, still have the instrument of simply acquiring fast-growing apps such as Instagram once they become too dangerous... Happy days for app developers...
